Men's Alpine Onset Merino 150 Quarter Zip

About this find

The Alpine Onset Merino 150 Quarter Zip is a base layer made from a soft, non-mulesed merino wool blend. It feels soft to the touch, dries quickly, and stretches with your body as you move. The quarter zip at the chest lets you open up when you warm up and close it again when the air turns cold.

Outdoor Research built this top with a lightweight construction that gives breathable warmth without the bulk. That makes it easy to wear under a shell or fleece for skiing, snowboarding, climbing, or hiking. It is also a good fit for a chilly morning workout or a bike ride, since the fabric is moisture-wicking and breathable.

Small details help it work hard in the mountains. Flat seams are made for chafe-free wear, and raglan sleeves give your shoulders room to move. Thumb holes at the cuffs help keep the sleeves in place, which is handy when you pull on a jacket or gloves.

The top also has UPF 30 protection, so you can peel off an outer layer on a sunny stretch and still have some sun coverage. Keep it as the first layer against your skin, then add a fleece or shell on top as the weather changes. It works as the foundation of a layering system for long days outdoors.
