The Smartwool Women's Classic Thermal Merino Base Layer Crew, formerly known as the Merino 250, is a high-performance staple engineered for extreme comfort in cold-weather conditions. Crafted from 100% responsibly sourced Merino wool, this base layer utilizes a heavy 250gsm interlock-knit fabric that provides exceptional warmth while naturally managing moisture and odors. The slim-fit design follows the body's natural contours to allow for effortless layering, while redesigned shoulder panels eliminate traditional top seams to reduce friction under heavy backpack straps. Raglan sleeves and back-to-front wrapping body seams enhance your range of motion, making it an ideal choice for skiing, hiking, or climbing. Finished with flatlock seams to prevent chafing, this thermal crew ensures you stay dry, warm, and comfortable during any outdoor adventure.
