The Oreus Jacket by Mountain Equipment redefines what's possible in cold-weather insulation. This revolutionary jacket utilizes exclusive Aetherm synthetic insulation, making it the warmest, lightest, and most compressible jacket in their lineup. Conquer big mountains and harsh conditions without sacrificing comfort or packing light – the Oreus is a true game-changer for alpine climbers and backpackers. The groundbreaking Aetherm insulation boasts an incredible warmth-to-weight ratio, exceptional loft, and outstanding packability. It keeps you toasty warm in the harshest alpine environments while stowing away into a compact size for easy backpack storage. The 100% recycled Plasma 10D outer fabric is incredibly lightweight and breathable. It's treated with a fluorocarbon-free DWR (durable water repellent) to shed light moisture and snow flurries, keeping you comfortable on the move.

The Mountain HC Insulated Hood offers complete adjustability to shield you from wind and snow. A 2-way YKK center front zip with a rear insulated baffle provides ventilation options, keeps warmth locked in and allows for easy access to your belay device. Stay organized with two zipped handwarmer pockets, a handy Napoleon chest pocket, and a pleated internal drop pocket that ideal for storing mitts. Elasticated cuffs and dual tether hem drawcords ensure a snug, comfortable fit that seals out the cold. When not in use, the jacket packs down into its own internal pocket with carabiner loops for easy attachment to your harness.
