Smartwool Men’s Classic Baselayer Bottom

Description Smartwool's Men's Classic Baselayer Bottom brings the time-tested performance of Merino wool to a midweight thermal silhouette built for cold-weather activity. The natural crimp of Merino fiber creates millions of tiny air pockets that trap and release heat dynamically, keeping you comfortable across changing output levels. The smooth, four-way stretch construction moves naturally with the body whether you're skinning uphill or descending a technical trail. A flatlock-seamed waistband and inseams sit flat under ski pants, softshells, and everything in between. Features –     Merino wool fiber provides dynamic thermal regulation –     Four-way stretch for unrestricted movement under shell layers –     Natural antimicrobial properties for multi-day use –     Flatlock waistband and seams sit flat under outerwear
