Meet our lightest, most technical down hoodie—the men'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
- Down-filled hood with rear adjustment lets you fine-tune the fit
- 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
- 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

Sizing Notes
Measurements are stated in inches unless otherwise indicated.
SHORT: Some pants are available in short sizes, which generally means an inseam that is 2.5 inches shorter than regular sizes.
TALL: Some pants, shirts, jackets and parkas are available in tall sizes, which generally means an inseam that is 3 inches longer and a rise that is 1 inch longer, a shirt or jacket body that is 2 inches longer, a parka body that is 2.5 inches longer and sleeves that are 2.5 inches longer than regular sizes.
Capri or cropped pants have an intentionally shorter inseam—reference the technical specs instead of this chart.
Inseam is measured to the floor.
