From frosty dawn patrol missions to freezing chairlift rides, the new Bassett Half Zip keeps you warm when it's cold—and breathes when things heat up. Blending the natural wicking and thermal magic of cruelty-free merino wool with a touch of stretch for mobility, we designed this gal to assure no overheating, no clammy chill, and no scratchy seams—just all-day comfort and core warmth, no matter what Mother Nature is dishing out. The 3/4 zip front offers easy ventilation when you're working up a sweat, while thumbholes keep sleeves in place and prevent bunching up when layering.
