It's time to regulate. The LITE Boxer Briefs are changing the way your body breathes. Made from superfine 19.5 micron merino wool and polyamide fiber, the Swedish-designed base layer provides superior insulation and moisture regulation in a garment that's strong and durable, while also smooth, stretchy, and odor-resistant. A minimal seam design, contrast stitching and a branded waistband add some flair to this fashionable underpiece. And it's functional, too, a must-have for any athletic pursuit that adapts to your temperature and activity level to keep you warm without overheating.
