Meet your new favorite cold-weather companion that effortlessly transitions from first tracks to après-ski. The Kari Traa Anna Half Zip combines 100% IWTO-certified merino wool with thoughtful Nordic design to create a women's base layer that performs as beautifully as it looks. The ultra-soft 19.5 micron merino wool naturally regulates your temperature whether you're carving turns or strolling downtown, while the strategic half-zip design and underarm ventilation panels let you fine-tune your comfort on the fly. Flatlock seams eliminate chafing during all-day wear, and the slim fit silhouette with distinctive Scandinavian-inspired patterns ensures you'll look as good at the lodge as you feel on the mountain. This isn't just another base layer – it's your ticket to staying comfortable and confident from slopes to streets all winter long.
