Meet our lightest, most technical down jacket—the women's REI Co-op Magma 850. Made with recycled nylon and high-quality goose down, it's a packable layer for backpacking and cold-weather adventures.
- 100% recycled ripstop nylon shell and lining fabric are both treated with a nonfluorinated durable water repellent (DWR) to help moisture bead up on the surface
- 850-fill-power goose down insulation provides a high warmth-to-weight ratio that packs down easily
- Goose down also has a DWR treatment so it repels water and dries fast to keep on insulating
- Variable baffles map insulation to the body, providing more warmth where it's needed and reduced bulk where it's not
- Elastic cuffs, drawcord hem and internal neck draft tube help seal in warmth
- Center-front zipper is backed by a windflap and chin guard
- Raglan sleeves and articulated elbows for ease of movement
- Zippered chest pocket utilizes hybrid insulation with polyester (98% recycled) to help preserve your device's battery life in the cold
- 2 zippered hand pockets, including one you can stow the jacket into for easy packability
- Hanger loop
- Machine wash warm in front-loading washer, gentle cycle; use down wash product; rinse thoroughly; do not twist or wring; remove promptly; do not use bleach or fabric softeners
- Tumble dry low with 2 clean tennis balls; remove and fluff after each cycle, returning to dryer until completely dry; do not line dry
