It all started with the signature PSD 7” brief. The 7” inseam and breathable sealed MicroMesh pouch offers tailored support for maximum comfort. With four-way stretch and durable flatlock stitching, your briefs will stay in place and moving with you no matter what you get into. Mystery pack bundles are curated to include a variety of styles, and we do our best to avoid duplicates. However, due to inventory limitations and the nature of the mystery selection, we cannot guarantee all items will be unique. Duplicate styles may occur.
