What Our Gearhead® Experts Are Saying: "The Vilma 1/2-Zip is one of those baselayers that never lets me down. It’s incredibly soft, super warm, and that half-zip design gives me the perfect amount of ventilation when I’m working up a sweat on the skintrack or layering up for a storm day." When cold mornings call for performance and comfort, the Kari Traa Vilma 1/2-Zip Baselayer is our go-to. Made from 100% merino wool, it keeps us warm even when wet, all while wicking moisture away for lasting comfort through shifting conditions. The jacquard-knit pattern adds subtle winter style, while the half-zip design lets us release heat during uphill pushes or layer adjustments. Stretchy underarm panels and raglan sleeves enhance mobility for skiing, hiking, or lounging fireside. With flatlock seams to prevent chafing and a soft high collar that seals in warmth, this ethically made piece blends technical performance with the luxurious feel of 19. 5-micron merino. It’s our trusted companion from basecamp mornings to summit missions.
