Women's Merino Wool Heavyweight Full-Zip

From the airport to the alpine zone — one zip, and you're ready for whatever the day throws at you.

The kind of layer that earns its place in your pack on every trip. The Women's Merino Wool Heavyweight Full-Zip is built on a 380 g/m² Ponte De Roma double-knit — durable, stretchy, soft against skin, and naturally flattering. It doesn't wrinkle on the plane, it doesn't stink after a long day on the trail, and it transitions from the trailhead to dinner without missing a beat.

Thumbholes keep your hands covered on cold morning starts. Yoked shoulder seams sit clear of your pack straps so you can layer it under a shell without the bulk. The YKK semi-auto locking zipper won't creep open mid-hike. And the zipper garage keeps hardware away from your chin all day long.

This is merino the way it's meant to be worn — not as a delicate base layer you have to baby, but as a real, hardworking mid-layer that goes everywhere and handles everything. Machine wash and dry. No drama.
