Active Boxer Brief Boxed

If your base layer is uncomfortable, your whole day goes sideways.

The Smartwool Active Boxer Brief (Men’s) is built to disappear under whatever you’re doing — running, hiking, travelling, lifting, or working long shifts. A Merino + recycled polyester blend manages sweat, controls odour, and dries fast, while the slim fit sits close without squeezing.

A double front panel adds support. Flatlock seams help prevent chafing. The soft elastic waistband stays put instead of digging in.

Light, breathable, and made to move — these are the boxers you forget you’re wearing (which is exactly the point).
