Patagonia Men's Down Sweater Hoody vs REI Co-op Magma 850 Down Hoodie - Women's

Warmth is critical for hiking in cold conditions, as it determines how well the jacket retains body heat during stops and movement. A higher fill power and better insulation distribution mean you stay warmer with less bulk. The REI Magma 850 edges out the Patagonia Down Sweater with its 850-fill down, which buyers consistently describe as the warmest jacket they've owned, even in temperatures as low as 25–28°F. While the Patagonia’s 800-fill down is still very warm and offers excellent insulation, users note minor cold spots along stitching lines. For hikers who prioritize maximum heat retention without added weight, the REI’s superior warmth-to-weight ratio makes it the clearer choice for extreme cold.

Fit affects both comfort and layering potential — a jacket that’s too tight restricts movement, while one that’s too loose lets in cold air. The Patagonia Down Sweater offers a contoured, precise fit that works well under shells and feels snug without being restrictive, with many praising its helmet compatibility and ability to layer comfortably. The REI Magma 850, while praised for its tailored look and waist cinch, draws more complaints about shoulder tightness and restricted arm movement, especially during climbing or reaching. For hikers who value a balanced fit that accommodates layering and movement, the Patagonia’s more forgiving cut gives it a practical edge.

Durability matters because hiking jackets face abrasion from packs, rocks, and brush — and a tear can ruin a trip. The Patagonia uses a 20D DWR-coated ripstop nylon with reinforced stitching and YKK zippers, though some users report feathers poking out or stitching snagging on rough terrain. The REI’s fabric is described as sturdy and water-repellent, with no major durability complaints despite fewer user reports overall. While both are reasonably durable for their weight, the REI’s slightly higher score and consistent feedback on fabric resilience give it a narrow advantage, though neither is built for extreme off-trail use.

Comfort determines how enjoyable a jacket is to wear for hours — from the hood design to cuff fit and fabric feel. The Patagonia Down Sweater stands out with an exceptionally soft, high-collar design, elastic wrist cuffs that seal out drafts, and a hood many call 'one of the best I've ever had' — praised for all-day wear and sun/rain protection. The REI offers a nice collar and storm baffle, but feedback on comfort is more focused on warmth than tactile or ergonomic details. For hikers who spend long days on trail and value a jacket that feels like a second skin, the Patagonia’s superior comfort features make it the clear winner.

Packability is essential for hikers who need to stow their jacket in a backpack when not in use — every cubic inch counts. Both jackets compress remarkably well into their own chest pockets, with users of both praising how compact they become. The REI Magma 850, at just 10.5 oz, packs down slightly smaller and is often described as 'ultralight,' while the Patagonia, though still highly compressible, is a touch bulkier due to its slightly heavier construction. For weight-sensitive trekkers, the REI’s edge in packability is meaningful; for others, both are excellent and won’t take up much space.

Mobility impacts how easily you can reach, climb, or adjust gear without feeling restricted. The Patagonia Down Sweater, despite its fitted cut, receives consistent praise for its helmet-compatible hood and freedom of movement, with no major complaints about arm or shoulder restriction. The REI Magma 850, while featuring gusseted elbows, draws more frequent complaints about tight shoulders and limited range during lifting or reaching — even users who like its warmth note it feels restrictive during high-mobility activities. For hikers who tackle technical terrain or need full arm mobility, the Patagonia’s superior movement makes it the more practical choice.
