Intraknit Boxer Brief - Men's

What Our Gearhead® Experts Are Saying:

"These are my go-to boxers for multi-day hikes and long travel days. They breathe better than anything else I’ve tried, and the mapped Intraknit zones keep everything feeling supported and cool without chafing. Total game changer in the comfort department."

We never underestimate the power of a well-built base layer—especially when it comes to our first layer. The Intraknit Boxer Brief Boxed brings the comfort of Smartwool’s signature Merino blend together with advanced body-mapped Intraknit™ technology for unmatched support, breathability, and freedom of movement.

This slim-fitting boxer brief hugs the body just right, with seamless zones of ventilation, articulation, and stretch that move with us on the trail, in the gym, or through airport security. Merino wool naturally manages moisture, odor, and temperature, while minimal seams reduce friction during long days in motion. It’s the base we want when we need to stay cool, dry, and focused.
