Icebreaker Merino Blend 125 ZoneKnit Boxer - Men's Black, S

What Our Gearhead(R) Experts Are Saying:"I wore these on a long, sweaty trail run in warm weather and never once had to adjust or readjust anything. The zoned knit construction really does regulate temperature where it counts, and the merino blend kept things fresh well past mile ten."A long run through rising heat tests more than just your legs, and the ZoneKnit Boxer from Icebreaker is built to handle the parts most base layers ignore. A merino and TENCEL Lyocell blend dries quickly and breathes easily, while zoned engineering places breathable eyelet panels exactly where heat builds fastest during hard effort. A double-layer front pouch adds support without added bulk, and gusset seamlines are positioned to eliminate the friction points that ruin a good run. Flatlocked seams throughout keep chafing out of the equation entirely, making this the kind of base layer piece built to disappear completely once the miles start adding up.
