Smartwool calls these “100% Merino. 100% capable,” and that’s stating fact. The Smartwool Merino 250 Baselayer Women's Bottom is a classic.. a 100% merino baselayer with the opacity to be used as leggings and the warmth you need under shells on winter days. Want to extend the range? The Norwegian trick is to pair a lighter baselayer under these, for a combination that has comfortable movement but impressive warmth. It’s the go-to trick we deploy if we want to wear shells in the low teens and creeping single digits. A baselayer that’s always ready for what's ahead and what's next, now with an updated fit to improve functionality. A midrise with a yoke waistband that won’t interfere with your pant’s waistband, flatlock seaming designed to minimize chafing, and a weight that means comfort is never in question. You can go out confidently in these knowing you’ve got insulation that won’t quit in an interlock knit that is breathable, thermoregulating, and even odor resistant. Pull a Smartwool sport skirt over these après ski and keep the day going without missing a beat. Stay warm, stay out there!
