Smartwool Classic Thermal Merino Base Layer 1/4 Zip Women's

When the forecast calls for bitter cold and you still want to get outside, this is the base layer that has your back, literally. The Smartwool Classic Thermal Merino 1/4 Zip is built from heavyweight 250-weight Merino wool, one of the warmest options in the Smartwool lineup, designed for skiing, winter hikes, and cold runs where staying warm actually matters. The interlock knit construction moves sweat away from your skin while trapping heat close to your body, so you stay warm without overheating during high-output efforts. A slim fit hugs your body for maximum warmth retention without bulk, while the crew neck and raglan sleeve design let you layer a shell or jacket over top without restriction. The 8 inch front zip with a semi-locking slider gives you quick temperature control when you climb hard on the way up and need to dump some heat, then zip back up for the descent. Flatlock seams keep chafing at bay no matter how many hours you spend in the backcountry, and because it is 100% Merino wool, you can wear it two days in a row without anyone knowing.
