Reviews
"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."
