Men’s Underwear

Pacsun’s Men’s Underwear collection brings foundation level comfort, everyday efficiency, and subtle style to your essentials. From classic boxer briefs and trunks to multi-packs and statement prints, this lineup gives you the kind of base layer that works behind the scenes—while still showing up when it counts.

Explore a range of fits and fabrics—soft stretch cotton blends, breathable micro-mesh pouches, four-way stretch knits, and waistbands designed for comfort and motion. Whether you’re stocking basics or adding bold prints to your drawer, the collection includes clean solids and graphic styles alike.

Style it your way. Choose solid boxer briefs under tailored trousers for a streamlined look, or pick color-pop prints underneath casual denim and a hoodie for street-ready flair. Mix multi-packs of basics with standout pieces so your foundation wardrobe is both functional and expressive. Layer with confidence, starting from the inside.

From weekday rotations to weekend comfort, Pacsun’s Men’s Underwear collection keeps you supported, styled, and ready for every moment. Browse the selection and choose the fits and prints that align with your ready-for-anything rotation.
