These pants are fantastic. I didn’t realize they were 100% cotton because I have sweated in them until they were soaked but as of yet they haven’t smelled sour like cotton t-shirts will. They stretch and move like a second skin and don’t pull down during leg work like squats/deadlifts. I want more colors/sizes. I just wish Machine Fitness would keep XL in stock on every product. I can’t spend more $ until they do! Highly recommend they pants. They only downside I’ve noticed is when I drag the bar up my shins for deadlifts, they pill quickly. The cotton does not like the gnarls on the bar at all. Favorite pants for gym, recovery, and looking sexy for my wife.
