I purchsed 4 pairs of airknit briefs, 1 silver tech briefs, and one t-shirt, but can't leave a review for some reason on the website because there's no option to input a review so I am leaving it here! The only thing i like are the silver tech briefs, everything else sucks for the price. First of all, they're all made in china and quality isn't top notch as you would expect for the price. Second, the fit is so damn weird and uncomfortable. If you wear your pants to your belly button, then you might like these underwear. The fit is old fashioned to the belly button and the legs below pouch are not long enough. I wish i didn't spend all that money on these stupid underwear that don't even fit well. I also use puma and adidas performance athetic briefs and those feel way better and a fraction of the cost!
