Product details:

A trusted companion for alpine adventures of any kind, the merino-insulated Hyperia Lite Vest provides a technical dose of core warmth in a compressible, lightweight design. The Hyperia's ultralight yet durable Pertex Microlight shell features a DWR finish that sheds variable conditions. Inside, we used our innovative MerinoLOFT insulation, a sustainable and high-lofting alternative to synthetic fills made from all-natural merino wool (up to 10% of which is recycled). MerinoLOFT retains warmth when wet and naturally helps regulate body temperature to keep you comfortable from high alpine hikes to mid-winter ski tours. Zippered hand pockets and an internal zip pocket store small essentials, offset shoulder seams eliminate chafing when you're climbing, skiing or hiking with a pack, and the vest stows in its internal pocket for compact carrying.
