  • 1. How long will Purpose gear last with consistent triathlon training and racing?

    All Purpose products — especially those with Hypermesh Pro — are built to endure the grind of serious triathlon prep. With proper care, they’ll hold their performance, fit, and structure through multiple seasons of racing, travel, and long training blocks.

    2. What makes Purpose Performance Wear stand out in triathlon and endurance sports?

    Purpose was made for athletes training in real-world conditions — heat, humidity, and high mileage. Hypermesh Pro fabric is lightweight, breathable, and fast-drying, offering race-day performance without compromising comfort. It’s trusted by elites across Asia and beyond for a reason.

    3. How should I care for my Purpose gear after a session or race?

    Rinse your kit right after training, then cold wash on a gentle cycle. Avoid softeners, bleach, and the dryer — hang dry only. The gear is tough, but a little care keeps the technical fabrics performing at their best.

    4. How does Purpose gear fit — is it true to size?

    Purpose is performance fit — streamlined, aero, and made to move with you during swim, bike, and run. It’s meant to feel close to the body without restricting movement. If you prefer a slightly looser feel or are between sizes, sizing up is a safe call.

Great suit!

In the US, the only downer was getting a bill for a tariff after delivery. Pay attention to the sizing conversion for US sizes, it was accurate.

I wore this for a sprint, olympic and 70.3 ironman triathlons this season. It was great not to have to think about sun exposure during the races.

The events I participated in were cold water swims requiring a wetsuit, and I tried wearing this suit underneath a wetsuit in training but it wasn't comfortable and felt bulky. For my events I pulled the suit on in T1 - the wrists and ankles are looser than the rest of the suit, so it was easy to pull on quickly.

The chamois is top-notch! I can't explain what makes it so much more comfortable than other brands but it's really great to ride in. I didn't do any events over 80F degrees, but I thought it was really comfortable in that amount of heat.

The only negative is that the material is a little fragile - it started fraying and pilling just from me wearing a backpack to walk back to my vehicle after the 3 events.

Overall really happy with the purchase.

Not what I expected.

I bought because of all the good reviews that I read on the website, but I am not sure why I do not feel like how others felt. 1st I wore it immediately when I received it and I wore it again after washing to make sure that how I felt was genuine. I wore it during intense indoor Pickleball games. I sweat a lot and the tshirt became soaked and it sticks to my body and I do not feel comfortable at all. I do not get it how almost all reviews that I read mentioned that they felt good wearing it. On the positive side, I love the colour and the cutting / shape.

Good stuff 😋

Material and fit feels very comfortable! At first I thought the thin padding will be very uncomfortable for longs rides but turns out it was super comfy! Would buy more of purpose performance wear products in the future :)

Excellent running top in hot, humid Singapore

The running tops by Purpose continue to perform well. This is my 3rd running top from Purpose. It is not only light weight, but it does not hold onto sweat, so it remains light and wicks sweat well. Great for training and racing.

Best suit ever bought

The BOREALIS - HYPERMESH™ SUPER SUIT absolutely lives up to the “super suit” name. From the moment you put it on, you can feel this was designed by people who truly understand high-performance racing in hot and humid conditions.

The standout feature is the Hypermesh™ fabric — insanely breathable, ultra-light, and incredibly comfortable even during long efforts. On hot race days, it genuinely helps regulate body temperature better than most suits I’ve worn. The airflow is noticeable, especially once you’re up to speed on the bike.

Aerodynamically, the suit feels fast. The fit is compressive without being restrictive, and the material moves naturally whether you’re climbing, in aero position, or running hard off the bike. It feels premium in every details.

If you race in tropical or humid climates, this suit is a serious advantage. Lightweight, breathable, fast, and visually stunning — easily one of the best tri suits I’ve used.

Highly recommended for athletes chasing PRs and wanting elite-level performance gear.

Comfortable and light Tri-suit

I’m really impressed with this tri suit. It’s incredibly comfortable and fits like a second skin without feeling restrictive at all. The material is light and breathable, which makes a huge difference during all three stages of a race. I didn’t experience any chafing, even over longer distances, which is a big win.

What stood out the most is how it manages to be both skin-tight and still the most comfortable tri suit I’ve worn. It moves really well with my body and doesn’t ride up or feel awkward when transitioning between swim, bike, and run.

I also love the colour. Overall, this is definitely my favourite tri suit so far and one I’d highly recommend.

Great suit

Extremely comfortable, great fit, no chafing and excellent for hot conditions.

Pretty Design PRICEY to EXCHANGE. Not worth the hassle.

Arrived QUICKLY to the US from Singapore. Well made with a nice design. The material is heavier and less breathable than I hoped/expected. Good for training but not all out in race conditions. The sizing feels close to US sizing if you prefer race level compression. NOTE: Exchanging costs as much as the kit from the US so be sure of the size you want.
Very polite customer service.

Best Tri Suit

This tri suit is very comfortable, good chamois. The fabric is very soft and stretchy. Lots of pockets to store ice if needed.
It looks also very cool.

Great piece of kit

I purchased one of these trisuits at the Ironman expo in New Zealand prior to my race. I was highly impressed by its performance and it really did help in keeping me cool during the race. It also looks fantastic. I would highly recommend and the 3XL sizing fit great for those of you who are very tall.

My first Tri-suit

OMG - this suit absolutely rocks!! After wearing running shorts and singlets (purpose of course) for IMNZ and in training, I was a little apprehensive to change for IMNZ 70.3. I shouldn’t worried, the pad is subtle but enough protection for cycling and not noticeable when running. The material is super breathable and soft against your skin, and the ice pockets, just next level thoughts in the design!! I can’t rate this suit highly enough!! Super happy and will def purchase again once this one has done its dash.
The only “issue” I had was the fit was a bit baggy around my waist (big hips, small waist), but a quick trip to a local seamstress had it fitting like a glove, so a super easy fix.

Light, Breathable, and Built to Perform

I’ve been wearing the Purpose Performance Wear shirt for my workouts and daily activities, and it has quickly become one of my favorites.

The first thing I noticed is how light and breathable the fabric feels. Even during intense runs or sweaty sessions, it dries fast and doesn’t feel heavy or sticky on the skin. The material is soft but still feels durable, so it doesn’t lose shape after washing.

Overall, this shirt really lives up to its name. It’s comfortable, functional, and versatile, perfect for anyone who wants performance wear that actually feels good and looks good too.

Beautiful Kit

I am very picky about the pads in my trikits and this one is one of my favorites. Slim but still padded and doesn't rub on the side of my legs while pedaling. The fabric is beautiful and keeps me cool in the warm weather. Pockets are the perfect size and quite snug against the body so you don't have drag while swimming. This is my second kit by Purpose and I love them both. Would buy again. Fits true to size. I am 5'2" and 115lbs and wear size S.

My first running singlet

I usually use event T's as my running shirt, was a bit apprehensive on getting this singlet but after having a look at KLSCM, was amazed by how thin the material feel and decided to invest one. Used it for a few times and love it! It is so light and airy that u forgot that u are wearing it!

Love these tops!

This is the fourth running top I have purchased from Purpose and I love them all. The material on the Hypermesh shirts is cool and comfortable. The cut for women is flattering and comfortable. I use these for both running and training in the gym and they are great - highly recommend!

At last…

Great quality, great fit, great feel, and comfortable across swim, bike and run especially in Southeast Asia. I like the design as well including the pockets. I wore it for an Olympic distance triathlon recently, but looking forward to test it out at Ironman 70.3 Langkawi in Nov.

Super high-end Trisuit

The suit has a great design and great feel. It serves exactly its purpose to be comfortable and fast in hot and humid condition. Definitely worth the $

The best & lightest running Singlet ever!

I love this singlet!! Since getting it I’ve not used any of my other singlets. Very light and soft to the touch. No chaffing and it feels like I’m not wearing anything. This feels like the best Singlet ever!!
