SmartWool Microweight Bottom - Men's

Wear the SmartWool Men's Microweight Bottom for temperate or warm-weather aerobic activities or as a next-to-skin base layer. Sweat cools you through evaporation. SmartWool's porous natural fibers move moisture in vapor form, creating a dry layer of air around your body that encourages evaporative cooling; you stay drier and more comfortable throughout your entire workout. By comparison, synthetics transport moisture in liquid form, wicking sweat before it evaporates, which means your skin never directly benefits from evaporative cooling. SmartWool fiber is also highly adaptable to a broad range of conditions; it keeps you warm in winter and cool in spring. This naturally anti-microbial pant features a covered elastic waistband, chafe-reducing flatlock seams, and a body-hugging fit.

Bottom Line: It might be Microweight, but it's big on performance.
