So comfy and good looking!

This is really a great tri-suit. Comfy and compressing and looks awesome. My only quibbles are that I personally don’t like a waist band and I just can’t get used to the feeling of fabric over my arms when I swim. Having said that - I also really like how it feels on!

Everything You Want in a Race Suit

I've raced in half a dozen suits from top brands in the last few years, and this merges the best features of each of them. The material is thin, sleek, and comfortable, and I love that the sleeves and legs end flat without seams, like an aero cycling kit. The one piece with a front zip looks like a cycling kit and feels as comfortable, and the chamois is just the right thickness. It's kept me comfortable throughout my rides and yet isn't noticeable on the run. The suit and the chamois both seem to wick moisture quickly, never getting waterlogged. And I love the pockets for nutrition, especially for longer races. For reference, I am a 5' 9", 165 lbs male, square shoulders but fairly slim, and a size small fits perfectly.

Amazing suit. Light, comfortable, and breathable. Padding is ample without slowing you down. Great on the bike and on the run. Can’t wait to get this in the water and see how it holds up in OWS.

Barley there and feels great

So this suit truly fits like a second layer of skin. I can't believe how thin the fabric feels while still offering compression. Although races are canceled right now, I've used this suit on the trainer in my house, on a run bike run brick workout and a 10 mile run. So far I'm extremely impressed I can't say enough for how great the fabric feels and how well it keeps me cool.
I've had the luxury of being able to get a new suit every year. So I've tried several different brands and I've become quite picky. This suit definitely met all expectations. A few of the things I love, large open collar for the wetsuit, full front zip for easy bathroom stops, the material is phenomenal, storage pockets are in just the right spot, compression cuffs at arms and legs don't pinch and are very comfortable. I highly recommend the suit.

Best Tri Suit out there

This is by far the best tri suit I have worn. The first time I wore this I felt like I could ride forever. Perfect amount of padding, zipper is very easy to use and the arms/chest fit nice and snug, yet comfortable. Everything you want in an aero suit. I think my favorite part of the kit is the amount of space the back of the suit offers for nutrition/flat kit.
