MaleBasics MB101 Everyday Cotton Trunk Men's Underwear

The MaleBasics MB101 Everyday Trunk is a cotton-dominant men's underwear built for all-day wearability, with a relaxed cut that avoids chafing elastic and legs that resist creeping throughout the day.

Made from 96% cotton and 4% spandex, this trunk leans into the classic comfort of cotton-rich fabric that breathes well, feels soft against skin, and provides a naturally easy fit without excessive constriction.

Available in a choice of colors from basic black to more individualistic options, the MB101 is the kind of underwear you simply put on and forget about.

Why choose a cotton-rich trunk for everyday wear?

Cotton-rich fabrics breathe better than synthetics and stay soft against the skin all day. The MB101's 96% cotton construction keeps you comfortable whether sitting at a desk or on the move.

Do the legs ride up?

No. The MB101 is specifically designed with non-creeping legs, so it stays in place throughout the day without adjustment.
