The Magma 850 is made from a 100% recycled ripstop nylon shell, which gives it a durable build that can withstand encounters with rocks and brush, and it has a DWR coating to repel light rain and keep it from soaking the jacket. Inside, it’s stuffed with 850-fill-power goose down for excellent warmth and low weight. The down also has a DWR treatment, which helps it retain its heat-trapping abilities even if moisture does manage to sneak through the nylon shell. Horizontal and angled baffles distribute the down where you need it most, while elasticized cuffs, a drawcord hem, and a draft tube at the neck keep chilly breezes at bay. Dual zippered hand pockets and a zippered chest pocket offer convenient storage, and the chest pocket is surrounded by polyester insulation specifically designed to keep your phone warm. Bottom line: REI really thought of everything when designing this jacket.
True to its name, the Magma 850 has impressed REI shoppers with its warmth, but also its "lightweight but durable" feel and hardiness in demanding conditions. “When you put it on you instantly feel the warmth,” said one reviewer. “Overall amazing jacket for everyday use or day hikes.”

Whether you wear it as a cozy mid-layer or on its own, the Magma 850 Down Jacket will be a reliable performer in frigid weather. Utilizing the time-tested insulating power of down and a robust recycled nylon shell, it offers an ideal blend of warmth, tough construction, and low weight—perfect for high-intensity activities this winter.
