What are the best tri-suits of 2026? We’ve tested the best suits on the market for your next triathlon

As the only bit of apparel that’s with you for every step of your race, the tri-suit (also called a triathlon suit) is a fundamental piece of triathlon gear. A tri-suit is a one-piece outfit designed for all three triathlon disciplines – swim, bike, and run—so you won’t need to change during the race.

With quick-drying fabric, rear padding, and clever features like zippers and rear pockets, it’s built for comfort, speed, and efficiency. Here at 220 Triathlon, we practically live in our tr-suits come race season. So read on for our guide to the best tri-suits on the market, including top options from Zone3, Huub, Orca, and Tri-Fit. Whether you’re racing a sprint or Ironman, on a budget, or looking for aerodynamic gains, we’ve tested the suit for you. Let’s get into it…

Best tri-suits tested for men and women

1. Tri-Fit Evo Next Gen

Tri-Fit’s debut Evo suit was just a couple of tweaks away from near maximum marks when I first tested it in 2019, and the acclaim keeps flowing with the Evo Next Gen into 2026. The suit builds on what made the Evo so good, the combo of Italian and German fabrics providing a silky-smooth internal experience and aerodynamic ribbed outer, with smartly-placed underarm mesh vents and superior leg grippers, adding to the winning composition.

The Next Gen again utilises the floating back pocket trick, which stops the pockets pulling on the suit when loaded, and yet there are swim benefits thanks to the side entry points. That said, stuffing gels into the stealthy hip pockets in T1 at speed is tricky. The pad is a reliable one and the finishing quality has been improved, but some might want more padding for Ironman. It features a great full-length zipper and garage, though.

2. Zone3 Aeroforce X II Short Sleeve Tri Suit

This new launch from Zone3 comes with futuristic graphics to match the tech used in its construction. A lot of aero development has gone into this suit and it shows, with dimpled sleeves, a textured fabric on the legs and the brand’s Aero Soft-Touch material on the front. Those aero credentials bore fruit in the wind tunnel, too, with the Aeroforce X II saving 48secs over our baseline suit when tested at 19mph /30km/h over 25mi/40km. It cuts through the water well, too, with noticeable beading up on the fabric’s surface.

I wasn’t such a big fan of the lack of cutaway zip, which makes toilet breaks a trickier affair, while the zip guard also wasn’t quite as comfortable or effective as we’d like. This mid-pack tester found the chamois too minimal for long-course racing, but elsewhere we were a fan of the flexibility on offer.

3. Castelli Core

Castelli, better known for cycling, proves its triathlon credentials with the Core tri-suit—an impressive alternative to its premium PR 2 Speed Suit. With an RRP of $180/£170, the Core delivers high-end comfort and construction with silky fabric, raw-cut sleeves, and GIRO4 leg grippers. The fit is close but forgiving, and sizing up is advised if you’re in between sizes.

The KISS Tri chamois is ideal for long-distance rides and remains comfortable on the run. A ¾ YKK front zip and spacious, drag-free rear pockets add to its long-course appeal. Overall, it’s a top-tier suit for both short- and middle-distance racing.

4. Bornbound Skärvatten Pro LD

Out of the box, the Skärvatten Pro LD offers far more than its good looks, with the lengthy legs and dimpled, laser-cut arm sleeves offering aero potential. The woven polyamide material sits softly on the skin, with further comfort coming from the full-length zipper and flatlock seam construction. It’s silky smooth on the swim – just like a second skin, dries fast on the bike and feels light on the run due to the breathability of the fabric. This is all down to the premium fabrics used in collaboration with Nalini to provide optimum aerodynamics.

Welcome race-day touches include the impressive leg grippers with silicone beads, a breakaway zipper for toilet stops and a pair of easy-to-access kangaroo-style pockets for stashing supplies. Unlike plenty of pads in this test, our men’s tester Matt says he would happily race Ironman in the wide and well-padded option here, yet it didn’t cause any hassle on the run either. 

Meanwhile, our women’s tester Sarah found the suit to be sleek and well fitting – true to size but you may want to size down if you don’t have a very long torso to avoid the arms and legs becoming too long. She experienced some chafing at the neck line (caused by a rough seam outside the zip garage) and modesty was occasionally compromised when adopting an aggressive riding position in the women’s suit.

Overall, the end result is an ultra-stylish suit that’s very, very hard to fault, and from a brand with a serious eco ethos. 

5. Zone3 Activate+ Short Sleeve tri-suit

The Zone3 Activate+ Short Sleeve tri-suit is impossible to miss thanks to its bold design (current colourways are blue fusions). It’s a solid, budget-friendly option packed with features borrowed from higher-end suits. The standout leg grippers stay secure without digging in, while longer sleeves add a small aerodynamic edge and help prevent them from riding up.

Comfort is a strong point: smooth seams, a soft feel, and a well-designed zip all help over multiple sessions. The slim chamois works well for shorter races but may lack cushioning for longer bike legs. Storage is minimal, with just one easy-access rear pocket. Breathability is decent, and the recycled materials are a nice touch. Overall, it’s best suited to sprint and Olympic distances—durable, comfortable, and great value, if you can pull off the loud look.

6. Tri-Fit Vanguard

The Tri-fit Vanguard is an excellent entry-level triathlon suit offering high-end features at a budget-friendly price. Its front-zip jersey design makes it easy to wear, while the ergonomic lower panels ensure a snug, aerodynamic fit. The breathable top dries quickly post-swim, and raw-edge legs with silicone grippers stay secure. The soft, lightweight chamois is ideal for shorter rides and is unnoticeable while running. Rear pockets are roomy and ventilated. A sturdy YKK zip adds quality, though the inner liner can catch slightly. Available in stylish colors, the Vanguard looks premium and performs well up to half-Ironman distance, perfect for 2026 racing.

7. Huub Pinnacle

Scoring a huge 93% from our male tester, Matt says: “The Huub Pinnacle slots in mid-way up the brand’s range of tri-suits but gives away little to range-topping models in performance or features. Fitting snugly and seemingly aerodynamically without compromising comfort, the Huub Pinnacle has a practical full-length zipper with an anti-chafing garage. You also get two large rear pockets absent from the Anemoi and Sub7 suits. It scores highly for breathability too and at such a competitive price, it’s tricky to think what the Pinnacle could do better.” Read my full Huub Pinnacle review for more.

Our female tester Sarah scored the suit 73%, here’s why: “The HUUB Pinnacle fits true to size in the body and the Open Zip construction means that it is easy to get on and off. It features longer arm lengths providing additional comfort on the bike and allowed for good shoulder movement in the swim. I found the legs were too loose and therefore I didn’t get a good grip from the silicone beading, which resulted in the legs curling up and rising whilst on the bike and running. The excess fabric bunching around the cycle pad and groin did lead to some discomfort and chafing.”

8. Tri-fit Vortex

The Vortex is Tri-Fit’s most technical suit yet, tested in the wind tunnel and displaying ribbed fabric on the arm sleeves and on a vast back panel, heat-welded seams and laser-cut sleeves. Heatwave-friendly features include an ice pocket and ventilation ports, UPF 35+ areas and an ultra-lightweight construction. 

The chamois is narrow and lithe, with a padded area around the perineum – I’d personally want more plumpness. The rear pockets are streamlined and can stash a handful of gels, although the gel pockets are tricky to load on the move. I’d go for the all-black version rather than the see-through white seen here (size-up if you’re between sizes too). That price tag is high ($558/£399), but in the era of $600/ £500+ tri-suits, this more than holds its own against the top-end contender.

9. Orca Athlex Aero Race Suit

We don’t look at the price tags of these suits until after the testing has finished and I figured the dimpled fabrics, superior meshing and breathability of the new Athlex would put it above the $250/£200 barrier. Happily, it’s well below that.

The cooling material composition and sizable white back panel also lend this one to warmer racing climes. Those aero dimpled sleeves are the business, while the pad is supportive yet supple on the bike and run. The covered rear pockets and stretchy material make this the one for non-wetsuit swims, although the swallow depth of the two rear pockets means that taller gels can dislodge. Points are also lost for lack of a zipper garage and the relatively basic leg grippers tend to move up and down the legs when cycling, though this is a mild irritation rather than a full-blown catastrophe.

10. Stolen Goat Venom Ibex Advanced

The Venom arrives with Stolen Goat’s trademark eye-popping design, and I like it. It also features plenty of well-crafted features, including silicone beads on the legs (chosen over a dedicated band) to hold the sleeves in place, raw-cut limbs and a full-length zipper garage. SG describe the fit as ‘serious’ and I’d suggest sizing up if you’re between sizes, but it’s not as tight as some race-focussed contenders as the 22% of elastane offers plenty of stretch.

That material boosts sizeable mesh panels on the back and sides for ventilation, while dimpled textures on the sleeves hint at aerodynamic gains (we’ve yet to test in a wind tunnel). The kangaroo-style duo of rear pockets are sizeable, the breakaway zipper great for pit stops and the pad can handle up to middle-distance length.

11. Trigirl Star Tri-Suit

Tri-Girl’s latest women-specific tri-suit impressed me more for its conscience than its cosmetics. Built from 100 % Econyl (recycled fishing nets reborn as tough nylon) it backs the talk with EU manufacturing, fair wages, and recycled packaging.

I sized up to suit my tall frame and found the extra length perfect; the soft Lycra cuffs stayed put, though they rolled when I tugged a wetsuit over them. The wide, vented neckline, slick zip and 4 mm chamois kept me chafe-free through sprint sessions. I’d recommend that long-course athletes should pick the thicker 8mm pad option. One rear pocket, optional bra, and a sub-£150 tag seal the budget tri suit buy.

What features should you look for in a tri-suit?

• Aerodynamics: For long-course racing, a sleeved tri-suit can save minutes on the bike leg thanks to reduced drag. It’s one of the most cost-effective speed upgrades, especially over 70.3 or Ironman distances.

• Fit and chafing: A good fit is non-negotiable. Avoid suits with excessive or poorly-placed seams, as they’re prime candidates for chafing during long races.

• Chamois padding: Padding should be minimal yet well-placed, with just enough to cushion the ride without feeling bulky or diaper-like on the run.

• Breathable fabric: Choose light, sweat-wicking materials that help regulate body temperature. Just note that these may require gentle care or hand washing between uses.

• Storage pockets: Fuelling is hugely important in triathlon, especially for the longer distances. Check for well-placed pockets that can hold gels and snacks without bouncing or sagging.

• Toilet access: For easier bathroom breaks, two-piece suits are practical. One-piece suits offer better aerodynamics and stability, but can be trickier during pit stops mid-race.

Frequently Asked Questions about tri-suits

How we tested these tri-suits

The triathlon suits here were all given multiple tests on the swim, bike and run to find the best one. Key factors included breathability, how fast they dried, chafing (or lack of), pocket sizing and accessibility, and the effectiveness of the leg grippers and zippers. The pad was assessed for how quickly it dried after the swim, its ability to provide comfort on the bike leg, and whether the size impacted on the run.

The price, aesthetics, durability and aerodynamics were also considered, as was the versatility of each suit. The first two suits were also tested for their aerodynamic abilities at the Silverstone Sports Engineering Hub’s wind tunnel with aero expert Stephen Roche (aka The Bike Tailor).

Wind tunnel testing involved speeds of 19mph/30km/h and 25mph/40km/h, with the test rider in the same aerodynamic riding position for each suit. We maintained a yaw angle of 7.5°, as this is often used as a baseline because it’s consistent with what you tend to experience on the road. The data in our testing results table above is for a 25-mile (40km) bike leg.
