I've tried Saxx, Underwear For Men (UFM), Sheath, and 2UNDR and Separatec are by far the most comfortable for me. They keep everything separated, no chafing or sticking, and feel like I'm wearing nothing. Great product!
Awesome boxer, I would say some of the most comfortable I have worn. Would definitely recommend and would definitely buy again.
Soft, smooth, just should have went one size smaller
