Modeled after the body-builder trunks of yore, the Flint and Tinder Trunk Brief gives all of the support of a brief, with just a bit more coverage around the thigh. They are made using 100% American long-staple cotton that actually gets softer with wear and topped with custom woven plush elastic. The goal is that from the minute you first put them on, through a lifetime of washing, you can feel the difference.
