When we designed the PrimeMan Trunk for men with average to smaller thighs, our goal was simple: support without restriction. And that went for every aspect of the underwear. You should have seen our whiteboard, filled with equations and diagrams like we were trying to fool Will Hunting. The legs had to be short but long enough to prevent chafing, yet secure enough not to roll up. The Micro Modal/Lycra blend had to be ridiculously soft but moisture wicking and anti-bacterial to prevent sweat and odor. And by God, we pulled it off. As for the anatomical pouch, it’s shaped to keep the penis and testicles nestled in place for unrivaled support – but somehow feels more freeing than going commando. We’d call it a miracle of science the likes of which have never been seen, but that’d be an understatement. For active men, the PrimeMan Trunk is perfection down to the last thread. The math, science, unending testing, and glowing testimonials prove it.
