Smartwool Merino Sport 150 Brief - Men's Black, M

We're wearing the Merino Sport 150 Brief on the trail, at the gym, or on the couch. Its performance-oriented fabrics ensure a soft and cozy feel down under, while a specialized design gives us that extra support we've been looking for. Plus, it's made with merino wool. That means it'll keep us fresh, dry, and ready for anything.
