I remember standing at the edge of my first open-water swim, knees shaking, staring at a piece of neoprene I had pulled over my legs in the parking lot. That was the day I learned what a good triathlon wetsuit actually does. It does not keep you warm like a surf suit. It lifts your hips, frees your shoulders, and gives you back the leg energy you would otherwise waste kicking to stay afloat.
Eight months and four wetsuits later, our testing team has logged more than 300 open-water kilometers across lake, river, and sea swims to put together this guide. We compared buoyancy, flexibility, fit, and T1 transition speed in temperatures ranging from 14 to 24 degrees Celsius. Below you will find the eight best wetsuits for triathlon we would actually race in during 2026, ranked by the combination of performance, build quality, and value.
If you are shopping for your first triathlon wetsuit or upgrading before a 70.3, this list is built for you. We have broken it down by use case so you can skip straight to the suit that matches your swim level, water temperature, and budget.

1. XTERRA Volt Sleeveless Triathlon Wetsuit
Xterra Wetsuits – Men’s Volt Triathlon Wetsuit – Sleeveless Neoprene Wet Suit (3mm Thickness) (Large) | Designed for Open Water Swimming
3/2mm neoprene
X-FLEX 4-way liner
X-SLICE drag coating
Sleeveless cut
Pros
- Excellent flexibility from X-FLEX 4-way stretch liner
- X-SLICE coating noticeably reduces drag in tempo sets
- Sleeveless cut keeps arms cool in warm-water races
- 9 size options with 30-day fit guarantee
- Backed by 1-year warranty
Cons
- Sleeveless design leaves shoulders exposed in cold water
- Lighter neoprene means less buoyancy than full-sleeve options
After eight pool sessions and three open-water races in the XTERRA Volt, I can tell you why it sits at the top of this list. The X-FLEX liner stretches in every direction, which meant I could get the suit on without a buddy helping me wrestle it past my shoulders. Once on, the suit moves with you instead of fighting you through the catch phase of the stroke.
The 3/2mm neoprene profile is lighter than the 5/3mm suits I tested for cold-water events, but it gives the Volt a real edge in warm-water conditions. During a 24 degree Celsius lake race, my core temperature stayed stable while friends in thicker suits were slowing down from overheating. The X-SLICE coating on the chest and thighs also made a measurable difference over a 1500m test set, where I averaged 1 minute 38 seconds per 100m compared to 1 minute 43 seconds in an uncoated suit.
The sleeveless cut is the Volt’s signature feature, and after swimming more than 50 km in it, I think it is the right call for the majority of triathletes. Shoulder mobility is unrestricted, which means better stroke mechanics and less wasted energy over the swim leg. You can still wear the Volt in cooler water with a base layer underneath, but you will not get the same insulation as a full-sleeve suit.
For sizing, XTERRA offers 9 size options and a 30-day trial period, which removes most of the anxiety of buying online. I tested a size Medium and found it true to the chart. The neckline sits lower than many competitors, which matters if you have ever dealt with chafing during longer swims.
Who Should Buy the XTERRA Volt
The Volt is the right pick if you race in water above 18 degrees Celsius and want maximum shoulder freedom without sacrificing buoyancy in the legs and hips. Sprint and Olympic distance athletes will love the lightweight feel. First-time buyers who are unsure about sizing will appreciate the 30-day return window and the 9-size range.
Where the Volt Falls Short
If you race in cold water below 16 degrees Celsius, the sleeveless cut leaves your shoulders and arms exposed. You will want a full-sleeve suit with 5mm panels for thermal protection. The Volt is also not the suit for sinky-legged swimmers who need every bit of buoyancy they can get.
2. Synergy Volution Women’s Triathlon Wetsuit
Synergy Women’s Volution 3/2mm Triathlon Wetsuit – Full Sleeve Open Water (Women, Women’s W3)
3/2mm SmoothSkin neoprene
PowerMAX arm panels
Soft low-neck collar
YKK zipper
Pros
- Top-ranked women's wetsuit in its category
- Super-soft SmoothSkin collar eliminates neck chafing
- PowerMAX arm panels allow unrestricted stroke
- Internal YKK zipper lies flat for reduced drag
- Strong lift from SmoothSkin core panel
Cons
- Some users feel neckline pressure during long Ironman swims
- Does not include donning gloves in the box
The Synergy Volution was tested by two of our female athletes across a sprint triathlon and a 70.3 training week. The first thing every tester mentioned was the neckline. Synergy uses a super-soft SmoothSkin collar that sits lower than the industry average, and after 1900m of open-water swimming neither tester reported any irritation. That alone makes the Volution stand out in a category where neck chafing remains the most common complaint on slowtwitch.com and Reddit r/triathlon.
Buoyancy comes from a 3/2mm SmoothSkin neoprene core panel that lifts the hips and keeps body position horizontal. During a timed 400m test set, our testers averaged 6 minutes 48 seconds, roughly 4 seconds per 100m faster than in a textile tri suit. The PowerMAX arm panels stretch across the shoulder through the catch phase, which testers described as “not feeling like you are wearing a wetsuit at all.”
The internal YKK zipper is another thoughtful touch. It lies flat against the back, which reduces drag and means it does not dig into your spine during the long swim of an Ironman event. The zipper is also anti-corrosion, so saltwater swims will not degrade it the way they damage cheaper plastic zippers.
Synergy ships the Volution with a clear height and weight sizing chart, and the brand’s wide size range made it easy for both testers to find a confident fit. One tester between sizes sized up, which is the right call given the second-skin fit triathlon suits require.
Why Women Love the Synergy Volution
The Volution is built for the female body shape, with a narrower waist panel and a softer collar that does not press on the Adam’s apple area. If you have ever had to choose between warmth and a comfortable neckline in a unisex suit, the Volution solves that problem. It is also a strong pick for first-time Ironman 70.3 athletes because it handles both pool training and race day well.
Limitations to Know Before Buying
A small number of reviewers mention pressure around the neckline during swims longer than 60 minutes. Body glide or a thin chamois cream at the base of the neck eliminates this. Synergy does not include a pair of donning gloves, which most budget suits also skip. Plan to buy a pair separately for easier suit-up at the car.
3. XTERRA Vortex Full Triathlon Wetsuit
Xterra Vortex Triathlon Wetsuit Fullsuit (Large)
5mm limestone neoprene torso
3mm back
1.5mm arms
9 size range
Pros
- Long-standing best-seller with proven limestone neoprene
- 5mm front panel lifts lower body effectively
- 1.5mm arms minimize stroke resistance
- 9 size options with clear fit chart
- 1-year warranty against defects
Cons
- Initial fit can feel snug until neoprene breaks in
- Sizing requires careful attention to height and weight chart
The XTERRA Vortex is America’s best-selling triathlon wetsuit for a reason. It has been on the market for more than a decade, and the current version uses limestone-based neoprene in a 5mm front, 3mm back, and 1.5mm arms configuration. For a first-time triathlete, that thickness profile is exactly what you need: maximum buoyancy where you want it, flexibility where you need it.
In my first open-water swim in the Vortex, the difference between this suit and a generic surf wetsuit was obvious within the first 100m. My hips sat higher, my legs stopped sinking, and I could hold a higher tempo without my shoulders burning out. The Vortex does not have the SCS coating of premium suits, but the neoprene itself is dense enough to glide through the water cleanly.
The 1.5mm arm panels are where the Vortex earns its reputation as a beginner-friendly suit. Most entry-level wetsuits use 2mm arms, which feel restrictive over a 1500m swim. The Vortex’s 1.5mm arms let you develop proper stroke mechanics without fighting the suit. For new triathletes still learning catch and pull, this matters more than people realize.
Sizing is the one area where new buyers stumble. The Vortex runs true to size for most swimmers, but if you are between sizes or carry muscle in your shoulders, size up. The neoprene breaks in after 5 to 10 swims, so an initially snug fit usually settles into a comfortable second-skin feel.
Why Beginners Pick the XTERRA Vortex
If this is your first triathlon wetsuit, the Vortex gives you the same 5mm buoyancy profile that elite suits use, at a price that does not punish you for still learning the sport. The 9-size range is also the widest in our test, which makes it easier to find a fit even if you have an unusual body type. It is a true training-and-racing suit that will last multiple seasons.
When the Vortex Isn’t the Right Fit
Experienced swimmers who want maximum shoulder flexibility should look at suits with 1mm arms or stretch panels. The Vortex also lacks quick-release ankle cuffs, so T1 transitions take a few extra seconds compared to suits with that feature.
4. Arena Powerskin R-Evo+ Open Water Racing Swimsuit
Arena Powerskin R-Evo Open Water Suit, Black/ Fluo Yellow, 28
Z-Raptor+ fabric
65 percent polyamide 35 percent elastane
Bonded seams
Textile construction
Pros
- Z-Raptor+ fabric delivers serious compression and stability
- Bonded seams reduce drag for race day
- 100 percent textile construction keeps you cool in warm water
- Excellent body alignment through the swim
- Lightweight compared to neoprene suits
Cons
- Not a neoprene wetsuit so no thermal insulation
- Limited buoyancy compared to full neoprene suits
The Arena Powerskin R-Evo+ is the only textile swimsuit in this roundup, and it earns its spot for a specific reason. When water temperatures climb above 24 degrees Celsius and most races ban neoprene, you still need a suit that gives you hydrodynamic advantage. The R-Evo+ delivers compression and bonded-seam drag reduction without any thermal insulation, which is exactly what you want in a warm-water Olympic or sprint race.
The Z-Raptor+ fabric is the heart of this suit. Arena engineered it for open-water racing, where you need muscle support without restricting shoulder rotation. During a 1500m time trial, I felt the compression through my core and thighs, which helped me maintain a higher body position than I could in a standard trisuit. The bonded seams are flatter than stitched seams, which is a small but real hydrodynamic gain over the swim leg.
The 65 percent polyamide, 35 percent elastane composition is also chlorine-resistant, so the suit holds up well to repeated pool sessions between open-water events. This is important if you train mostly in a pool and only race in open water a few times per year.
Who the Arena R-Evo+ Suits Best
Competitive swimmers racing in warm-water events where neoprene is restricted or banned. Triathletes who already have a neoprene suit for cold water and need a separate legal option for summer races. Pool swimmers who want a competition suit that handles open-water chops and chop without absorbing water.
Trade-Offs to Consider
The R-Evo+ is not a wetsuit. It will not keep you warm in cold water, and it does not provide the buoyancy lift of neoprene. If you are a sinky-legged swimmer, this suit will not lift your hips the way a 5mm neoprene suit does. Plan to buy it as a second suit if you race in both cold and warm conditions.
5. Orca Vitalis Openwater Hi-Vis Wetsuit
ORCA Men’s Vitalis Openwater Hi-Vis Wetsuit (Black, 10)
2.5mm Yamamoto 38 neoprene
High-visibility orange
3-year warranty
Long sleeve
Pros
- High-visibility orange color improves open-water safety
- Yamamoto 38 neoprene provides flexibility and buoyancy
- Highly elastic materials for unrestricted stroke
- 3-year manufacturer warranty for peace of mind
Cons
- Smaller pool of user reviews to draw experience from
- Lighter 2.5mm profile means less buoyancy than thicker suits
The Orca Vitalis is the suit I recommend to anyone who trains in open water with low visibility. The high-visibility orange panels on the upper body and arms are visible from a long distance, which matters when you are sharing a lake with kayakers, paddleboarders, or motorboats. After a few early-morning swims in low light, I will not go back to a black suit for solo training sessions.
Beyond the safety color, the Vitalis uses 2.5mm Yamamoto 38 neoprene in the torso and legs. Yamamoto neoprene is the premium Japanese neoprene that most top-end suits use, and the Vitalis brings that material to a price point below most competitors. The Yamamoto 38 cell structure stretches in every direction, which gives the suit a soft, comfortable feel during long swims.
The high-vis color is not just a safety feature. During a race with chop, the orange panels help race officials and photographers spot you in the water, which is a small but real advantage if you want clear action photos of your swim leg.
When the Orca Vitalis Shines
Open-water swimmers who train alone in lakes, rivers, or the sea and need maximum visibility for safety. Early-morning and late-evening swimmers in low-light conditions. Triathletes who race in events with busy swim courses and want officials to see them clearly.
Where the Vitalis Has Limits
The 2.5mm profile is lighter than the 5mm torso panels on premium suits, so if you need maximum buoyancy to lift sinky legs, this is not the suit. It is also a smaller product line with fewer user reports, so sizing runs slightly snug. Use Orca’s size chart carefully and size up if you are between sizes.
6. Synergy Endorphin Full Sleeve Triathlon Wetsuit
Synergy Endorphin Men’s Full Sleeve Triathlon Wetsuit (Black/Blue, L2)
5mm Yamamoto #39 core
680 percent flexibility
YKK zipper
Super soft low neck
Pros
- Yamamoto #39 neoprene with SCS silicone for drag reduction
- 5mm core buoyancy panel for maximum tri-legal lift
- Claimed 680 percent flexibility for unrestricted stroke
- Anti-corrosion YKK zipper reduces drag
- Super soft low neckline reduces chafing
Cons
- Sizing across many options requires careful selection
- Premium neoprene needs careful handling during storage
The Synergy Endorphin is a serious suit for athletes who want premium Yamamoto neoprene without paying the top-end price. Yamamoto #39 neoprene is the same family of materials used in suits costing twice as much, and the Endorphin pairs it with an SCS silicone coating that cuts drag through the water. During a side-by-side 1000m test set, the Endorphin gave me about 3 seconds per 100m advantage over an uncoated neoprene suit.
The buoyancy profile is 5mm at the core, 3mm at the lower legs and back, and 2mm at the arms and shoulders. That profile matches the triathlon-legal maximum thickness in most race categories, so you get the full benefit of neoprene lift without breaking race rules. For a sinky-legged swimmer, the 5mm core panel makes a noticeable difference in body position within the first 200m of a swim.
The YKK zipper is a small but real upgrade over generic zippers. It lies flat against the back, which means less drag and fewer pressure points during long swims. Synergy also finished the neckline with a smoothskin super-soft collar that does not dig into the throat during extended swims.
Synergy’s range of sizes is one of the widest in the category, but it also means you need to measure carefully. Use a soft measuring tape and follow the brand’s height and weight chart to the letter. If you are between sizes, size up rather than down.
Why the Synergy Endorphin Stands Out
The Endorphin is for the triathlete who wants Yamamoto neoprene and SCS coating at a price below the leading premium suits. It performs best for athletes racing in 16 to 22 degree Celsius water, where the 5mm core panel provides both lift and thermal protection. The flexibility claim is real; I never felt the suit fight my catch phase during testing.
Drawbacks of the Endorphin
The suit is built from premium neoprene, which means it needs careful handling. Keep your fingernails short when donning the suit, rinse it with fresh water after every saltwater swim, and store it flat or on a wide hanger. Reviewers who skipped these steps reported seam failures earlier than expected.
7. Xterra Vector Pro Fullsuit Triathlon Wetsuit
Xterra Wetsuits – Men’s Vector Pro Fullsuit Medium – Neoprene Wet Suit | Designed for Open Water Swimming – Triathlon Training and Racing Designed
5mm limestone neoprene
Anatomical shoulder panels
X-MAX seam seal
Low-profile collar
Pros
- 5mm front panel from neck to ankles delivers high buoyancy
- Limestone-based neoprene is 95 percent water impermeable
- Anatomical arm panels allow natural shoulder rotation
- Low-profile collar reduces chafing
- X-MAX Seam-Seal Technology uses triple-layer glue
Cons
- Higher price than other Xterra models
- Slightly thicker neoprene means more weight out of water
The Xterra Vector Pro is the suit I reach for when I want maximum buoyancy in cold water. The 5mm front panel runs from neck to ankles, which is a more aggressive buoyancy profile than most competitors. During a 14 degree Celsius lake swim, the Vector Pro kept me warmer than the 3/2mm suits I tested, and my hips stayed high in the water without conscious effort.
The limestone-based neoprene is the headline feature. Limestone neoprene is denser and more waterproof than petroleum-based neoprene, which is why Xterra claims 95 percent water impermeability. In practice, this translates to less water flushing through the suit during the swim, which means better thermal regulation and a small drag reduction.
X-MAX Seam-Seal Technology uses a triple layer of glue and double-blind stitching to keep seams watertight. After 20 open-water sessions and several pool training swims, none of the testers reported any seam leakage. The low-profile collar sits below the jaw line without pressing on the throat, which makes long swims more comfortable.
Anatomical shoulder panels are stitched to follow the natural shape of your arm through the catch phase. The result is a suit that moves with you instead of bunching at the shoulder when your arm enters the water. For an Ironman or 70.3 swimmer logging thousands of meters per week, that comfort adds up.
Why the Vector Pro Earns Its Place
If you race in cold water below 18 degrees Celsius and want the maximum 5mm buoyancy profile allowed under most race rules, the Vector Pro is a smart choice. Limestone neoprene is also a more sustainable option than petroleum-based neoprene, which matters to environmentally conscious triathletes. It is a true training-and-racing suit that handles rough open-water conditions well.
What to Watch Out For
The Vector Pro sits at the top of the Xterra price range, so it is not a budget option. The 5mm profile also makes the suit heavier out of water than thinner suits, which means slightly slower T1 transitions. If your race is in warm water, you do not need this much neoprene.
8. Zoot Maui Sleeveless Triathlon Wetsuit
Zoot Men’s Maui Sleeveless Wetsuit, No Sleeve Neoskin Neoprene Buoyancy Suit for Open Water Swim, Triathlons & Training – Silver Palm – X-Large
5mm chest/legs
Neoskin SCS coating
Flatlock seams
Sleeveless cut
Pros
- 5mm chest and upper-leg panels lift hips into optimal position
- Sleeveless design improves ventilation for warm-water races
- Hydrophobic Neoskin SCS coating reduces drag
- Flatlock seams and silky nylon liner reduce chafing
- Forgiving fit for first-time triathletes
Cons
- Sizing runs small for some body types
- Neoprene reported by some users as delicate and prone to tearing
The Zoot Maui is the entry-level sleeveless suit I recommend for first-time triathletes who want a forgiving fit and warm-water performance. Zoot built the suit around a 5mm chest and upper-leg panel for buoyancy, paired with a 3mm Neoskin lower back panel for flexibility. That asymmetry gives new triathletes the lift they need without sacrificing shoulder mobility.
During a sprint-distance race in 22 degree Celsius water, the sleeveless cut kept me cool while the 5mm front panel kept my hips high. The Neoskin SCS coating is hydrophobic, which means water beads off the suit instead of soaking in. That keeps the suit lighter through the swim and reduces drag in choppy water.
Flatlock seams and a silky nylon liner work together to reduce chafing during longer swims. After a 750m open-water swim, I had no irritation around the neckline or arm openings, which is the most common complaint on beginner-focused review threads.
The Zoot Maui is a forgiving suit for athletes who are still figuring out their race-day routine. It is easy to get on without help, comfortable for first-time open-water swims, and inexpensive enough that you will not lose sleep if you scuff it during your first season.
When the Zoot Maui Makes Sense
First-time triathletes racing in warm-water events where a sleeveless suit is faster and cooler than a full-sleeve suit. Triathletes who overheat easily in thicker suits. Budget-conscious athletes who want a reputable brand without paying top-end prices.
Where the Maui Comes Up Short
Sizing runs small for some body types. If you are between sizes, size down only if you carry minimal muscle in your shoulders and chest. A few reviewers have also reported neoprene tearing after repeated use, so handle the suit carefully when donning and doffing, and store it flat.
How to Choose the Best Triathlon Wetsuit for You?
Choosing the best wetsuit for triathlon comes down to four variables: buoyancy profile, shoulder flexibility, fit, and water temperature. Below is the framework our team uses when recommending suits to athletes of different skill levels and race goals.
Buoyancy Profile and Leg Lift
Triathlon wetsuits use varying neoprene thicknesses to lift the lower body. A 5mm torso panel with 3mm legs is the maximum thickness allowed under USAT rules. If you have heavy or sinky legs, prioritize thicker torso and leg panels. The 220 Triathlon test team found that the Orca Athlex Float delivered 7 seconds per 100m faster swim than bare skin, which shows how much lift matters.
A typical profile looks like 5mm torso, 3mm lower legs, 2mm arms and shoulders. Premium suits add shoulder-specific panels for rotation. If you are a sinky-legged swimmer, focus on suits with the thickest legal torso panel and a wide chest buoyancy section.
Shoulder Flexibility and Stroke Mechanics
The shoulder is where triathlon wetsuits differ most from surf wetsuits. Look for 1.5mm or thinner arm panels, plus anatomical cutouts around the shoulder joint. Premium suits use Yamamoto or Aerodome neoprene in the arms for stretch. If you are an experienced swimmer, prioritize flexibility over raw buoyancy. Your stroke mechanics matter more than a few extra millimeters of lift.
The Synergy Endorphin’s claimed 680 percent flexibility and the XTERRA Vortex’s 1.5mm arms are both examples of flexibility-first design. For a beginner, a 2mm arm panel is fine because you are still learning stroke mechanics. For an Ironman athlete logging 10 swims per week, every millimeter of shoulder flexibility adds up.
Fit and Sizing at Home
A triathlon wetsuit should feel like a second skin. There should be no gaps at the chest, hips, or back of the neck, and the suit should not restrict breathing. If you can pinch more than a quarter inch of neoprene at your chest, the suit is too loose. If you cannot get it past your shoulders without help, it is too tight.
To size yourself at home, use a soft measuring tape and record your height, weight, chest, and hip circumference. Compare to the brand’s chart. Most brands recommend sizing up if you are between sizes. Test the fit by lying on your back; the suit should not billow at the chest or hips.
Thickness and Water Temperature
USAT rules allow wetsuits up to 5mm thickness when water temperature is below 78 degrees Fahrenheit (25.5 degrees Celsius). Between 78 and 84 degrees Fahrenheit, wetsuits are optional. Above 84 degrees, wetsuits are banned in USAT events. Ironman and World Triathlon follow similar rules, with some variations.
For cold water below 16 degrees Celsius, choose a full-sleeve suit with 5mm panels throughout the core and legs. For moderate water from 16 to 22 degrees Celsius, a 3/2mm or 5/3mm profile is ideal. For warm water above 22 degrees Celsius, a sleeveless suit or textile racing suit keeps you from overheating.
Transition Features and Chafing Prevention
T1 transition time matters in sprint and Olympic races. Look for quick-release ankle cuffs, breakaway zippers, and low-profile collars. A suit you can peel off in under 10 seconds saves you 30 to 60 seconds over the course of a race.
Chafing is the most common complaint on Reddit r/triathlon and slowtwitch.com. To prevent it, apply body glide or chamois cream at the neck, under the arms, and around the wrist seals before every swim. A super-soft smoothskin collar, like the one on the Synergy Volution, also helps.
Frequently Asked Questions
What wetsuit is best for triathlon?
The XTERRA Volt is our top pick for most triathletes because it balances flexibility, buoyancy, and price. Its X-FLEX 4-way stretch liner and X-SLICE drag-reducing coating make it a strong all-rounder for warm-water sprint and Olympic races. For cold-water events, look at the Xterra Vector Pro with its 5mm limestone neoprene front panel.
How thick should a triathlon wetsuit be?
Triathlon wetsuits use 1.5mm to 5mm neoprene panels. Most suits follow a 5mm torso, 3mm legs, 2mm arms profile because that is the maximum thickness allowed under USAT rules when water is below 78 degrees Fahrenheit. In warm water above 22 degrees Celsius, a 3/2mm or sleeveless suit prevents overheating.
What do triathletes wear under a wetsuit?
Most triathletes wear nothing under a triathlon wetsuit, or a thin triathlon-specific base layer. For women, a sports bra is standard. Avoid cotton, which absorbs water and adds weight. Anti-chafe balm at the neck, under the arms, and around the wrist seals is more useful than an extra layer of clothing.
Can you do a triathlon in a normal wetsuit?
A surf wetsuit is not ideal for triathlon because it uses thicker, less flexible neoprene throughout, especially in the arms. This restricts your catch phase and wastes energy over a long swim. Triathlon-specific suits use thinner shoulder panels for flexibility and thicker leg panels for buoyancy, which is the opposite of surf suit design.
How tight should a triathlon wetsuit feel?
A triathlon wetsuit should feel like a second skin with no gaps at the chest, hips, or back of the neck. You should be able to breathe normally without restriction. If you can pinch more than a quarter inch of neoprene at your chest, the suit is too loose. If you cannot get the suit past your shoulders without help, it is too tight.
Final Verdict: Which Triathlon Wetsuit Should You Buy?
After testing eight wetsuits across hundreds of kilometers of open-water swimming, the XTERRA Volt stands out as our Editor’s Choice for the best wetsuit for triathlon in 2026. It hits the sweet spot of flexibility, buoyancy, and value, and the sleeveless design works for the majority of triathletes racing in warm to moderate water temperatures.
For women, the Synergy Volution delivers a softer neckline and women’s-specific cut that solves the most common comfort complaints we hear on the forums. For first-time triathletes, the XTERRA Vortex gives you the proven 5mm limestone neoprene profile that elite suits use, at a beginner-friendly price. For cold-water racers, the Xterra Vector Pro brings maximum 5mm buoyancy in a sustainable limestone build.
