Great design, most comfortable product.
I have several pairs of Sheath trunks. This was my first purchase of a bamboo fabric, and it was well worth the extra amount. Very comfortable, smooth feel yet a bit sturdier than the micro-modal products. I expect to upgrade all my next purchases to this fabric. I have long been sold on the product's pouch design.


Favorite brand of underwear
I have the 8” boxers and the briefs. The 8” boxers tend to get bunched up around my upper thigh especially if I’m doing any sort of crouching, squatting or climbing stairs. I do workout a lot and my thighs are pretty thick so maybe that has something to do with it. With the 2.1 boxer there is significantly less bunching. With the briefs, there is obviously no bunching. With all the different cuts Sheath has the sizing is true and the best part is the separation of your junk. No more stickiness, constantly adjusting or chafing, just a quick adjustment when you go from sitting to standing.


The only pair I purchased that missed the target.
I’m am a loyal owner and customer of many pair of Sheath underwear. I purchased the bamboo pair. They feel great, however they do not hold their shape and the support dissipates quickly after wearing for a short amount of time.
