Great undies
"These are the best boxer briefs you can buy. Fit perfectly. The pouch is unlike any other I’ve tried. No adjusting the boys whatsoever and they even enhance the bulge, which is a plus!"

Great underwear
"These are a great pair of underwear! They don't ride up and they keep your package in one spot. Great for working out and sports."
"Love these, very comfortable material and seem to breath well !!"
"Fit is great and comfortable"
"Aleays the best"
What I’ve been looking for…
"Since my previous go-to boxer briefs were discontinued a few years ago, I’ve been trying out different ones. These are the closest to the old ones I’ve found yet. I really like the separation from the 3D pouch. I don’t get any uncomfortable pinching whether lifting weights or riding my MTB."
"Great fit"
BN3TH is all I want to wear now
"The fabric is better than just cotton. Cotton is rotten. This stuff is soft, breathable, and cool. Technically, I should wear a Large. The high-activity style in Large fits me perfectly. The regular style is ok in large, but I prefer the fit to be a little tighter so the boys don’t go flopping around. My only suggestion is to get rid of the sewn labels and go to printed. Cutting off labels makes me nervous."
