Eating for tri? Sleeping for tri? It's time to dress for tri.

Targeted compression zones, Coolmax wonder fabric, and mesh panels make the CW-X Ventilator Tri-Short a favorite among triathlon athletes, trainers, and runners alike. In the Tri-Short, CW-X addressed the most notorious ailments of the triathlete by using the CW-X Support Web: a unique targeted support system for hip flexors, the core, and the back.

  • Support Web design targets the core and upper legs with support for improved circulation, less fatigue, and accelerated recovery
  • Coolmax fiber-based moisture managing material evaporates perspiration quickly, letting you remain cool in times of serious training
  • UPF 40-rated fabric helps when the sun beats down all day
  • Strategically placed mesh ventilation panels let hot air flow out and cool air enter
  • Flatlock seam construction means no hot sorts along the seams to rub you wrong

C-WX Ventilator Tri shorts review

Ran 5 miles in them & not going back to shorts.
I might wear them in da hot tub!

I'm 5'11, and still growing. Weigh 130lb. at the moment I'm probably a Small... but if I grow, show I just get the Medium?

Also - will the chamois be annoying when running, or it is unnoticeable?


Responded on

Tim, I run in these all the time - mostly when I go out for several hours on the trail. The chamois is completely unnoticeable so that is no problem. Totally comfortable and never any chaffing. As for size, going with their sizing chart, I am at the low end of Large and they fit very snuggly so you might be able to get away with a medium.

Great all around compression short

  • Familiarity: I've put it through the wringer

I've got another pair of CW-X compression but they are just too hot for warm days. These are great - good ventilation and excellent support. Never feel too hot on warm days. Great for long runs and all day skiing or hiking outings.

are these shorts ok to wear also for the swimming leg of the triathalon? thanks!

They're a good material to get wet because they'll dry pretty quickly, but I'd be slightly concerned about chafing if you jumped straight on a bike with them. Although I don't know if there's any material that won't do that, so these are as good as any.

Not Just Tri..

  • Gender: Male
  • Familiarity: I've used it several times

I am not a triathlete by any means. I do however Ski, Bike and Hike alot. These are my go to "underwear" whenever I'm hiking, spring skiing, or just using them for muscle recovery from bike rides.

I have a couple of sets of compression shorts, and these are by far the most comfortable. I'm 6' 175lbs 34" waist and the Large fits me perfect. The crotch has a fleece chamois that is very comfortable to wear. I've worn these multiple days at work and they do no irritation to me.

I wish I had two sets, but at almost $90 a pop thats a little steep.

Excellent Tri-top

Haven't really tried other tri-tops but this one is just awesome. Tried swimming in it. Definitely feel the support. I don't feel the need to swear something else underneath. Will yet to try how it feels riding the bike with it but I would not expect to run into any problems. The material is thick enough for that purpose as well.

What size should I order for a 34-36 waist?

Best Answer Responded on

All depends on height and weight. I am about a 34 waist, 163lbs, 5'11. I wear a medium. if you are heavier...more than about 173lbs, I would go to a large size. Hope that helps.

Question for the CW-X rep, could you upload a photo of the chamois? I'm assuming it does have one...?

Responded on

The Chamois is like a fleece non-padded, feels very good on the lowers.
