We created the Evergreen Zip-Up for the minimalist who wants the core comfort of a onesie without the interference of a hood. Whether you're using it as a sleek base layer on the ski hill or as a more polished look around the cabin, this piece keeps all our signature features—like the half-moon butt flap and ZIP liners—while adding functional upgrades like thumb holes for extra warmth.
