Whether you're running in frigid temps or skiing in blustery winds, the Men's Merino Sport 250 Wind Boxer Brief helps keep you covered—comfortably. Smartwool has made the warmest Merino/poly-engineered material to help move sweat, dry quickly, and hold its shape during your highest-intensity activities. A windproof front panel provides increased protection as temps drop and minimal Merrow seam construction provides superior durability while keeping super-soft Merino next to skin. Grab a pair and make your first layer your favorite.
