Featuring an unmatched combination of warmth, lightweight packability and protection that’s crucial for alpine pursuits like climbing, skiing and trekking, the Hyperia Lite Jacket offers technical performance with natural merino insulation. The Hyperia’s ultralight yet durable Pertex® Quantum Air shell features a DWR finish that sheds variable conditions. Inside, Icebreaker uses 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 everywhere from local rock climbs to backcountry hut trips. Zippered hand pockets and an internal zip pocket store small essentials, offset shoulder seams eliminate chafing when you’re moving with a pack and the jacket stows in its internal pocket for premium packability.
