WHAT OUR ATHLETES SAY
ZACH MILLER | Ultra Runner
"I've tested them in all sorts of conditions: wet, dry, hot, humid, cold - en route to winning the Trail 100 Andorra, for 20 hrs to finish second at Tour Du Mont Blanc, and for 3+ hrs at the 40k world championships in Thailand. To sum it up,
I’ve put them through the ringer and I like what I’ve found".
DEONTAY WILDER | Heavyweight Boxer
"When I first saw the underwear, I noticed the design of the muscle mirroring and I thought it was very impressive! It is unique and I’d never seen it on underwear before. I wanted immediately to put them on and try them!
I like what it does for me - the tightness of it when I perform, it fits me just right and gives me the flexibility I need".
STUART G | CXP Community
"These are the most comfortable chafe free under shorts I have ever tried. No going back.
I will be replacing all of my sports underwear with CXP."
MEN'S FITNESS | Rated CXP Best Underwear
"For endurance sports you need unfaltering comfort and durability and CXP delivers in spades…" Support: 5/5. Comfort: 5/5. Durability: 5/5.
OVERALL: 5/5.
PAUL C | CXP Community
The 7" is my favourite of the two lengths, helped in no small part by the leg grippers which actually do their job and prevent any riding up - even during pre/post stretching.
The updates are fantastic!
RICHARD P | CXP Community
"They are exceptional. I felt nothing (which is excatly what you want to feel). Quality is incredible, and the fit is perfect.
Seriously impressive product".
