Back by popular demand, the Alpine Onset Merino Base Layer Collection is made up of a soft merino wool blended with a recycled polyester for added durability and moisture management.

Merino wool base layers are skiers, snowboarders, and winter enthusiasts' favorite material for good reason. That's probably why customers like you demanded a revival of the Alpine Onset Merino Collection of merino wool base layers, but this time, with a twist - by adding a recycled polyester for added durability and moisture management. Fit to be worn next to skin, and built with a no-chafe flat seam construction, the naturally anti-odor properties of the Alpine Onset Collection make them a great choice for multi-day trips, extended backcountry adventures, and activities where layering up without overheating is key to safety and success.
