Pure 100% Merino wool with an interlock knit gives the Smartwool Women's Classic Thermal 250g Merino Baselayer Bottom a smooth, next-to-skin feel with natural temperature regulation, moisture management, and odor resistance. The fabric balances warmth and breathability for consistent comfort through cold starts and high-output laps.
A slim, body-following fit pairs with a mid-rise waist and Merino-lined elastic waistband to sit cleanly under shells. Flatlock seam construction minimizes chafing, while a 30.5" inseam in size medium keeps the Smartwool Women's Classic Thermal 250g Merino Baselayer Bottom moving comfortably all day.
