A technical hooded insulator designed for climbing, skiing and other mountain pursuits where you need both warmth and lightweight packability, the Hyperia Hooded Jacket is an alpine essential. The Hyperia’s ultralight yet durable Pertex® Microlight shell features a DWR finish that sheds wind and light precip when conditions change unexpectedly. 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, whether you’re belaying on a multi-pitch climb or skinning along a backcountry ridgeline. The snug-fitting hood blocks the weather and adds insulation, zippered hand pockets and an internal zip pocket store small essentials, and offset shoulder seams eliminate chafing when you’re wearing a pack.
