Our take on the REI Magma 850 Down Jacket

The REI Magma 850 is a lightweight down jacket built around 850 fill-power down, so it packs small and traps heat well for its weight. The unhooded version weighs about 11 oz and uses a recycled nylon and polyester shell with raglan sleeves that keep seams off the shoulders. It sits between ultralight down sweaters and heavier parkas: warmer than a 650-fill layer, far lighter than a bulky puffer. It suits cold-weather hikers, backpackers and city wearers who want warmth without bulk, and owners generally rate the warmth-to-weight ratio highly.

Questions and answers

How warm is the Magma 850 compared with other down jackets?
It is warmer than most 650-fill down sweaters and close to premium 800-fill jackets, thanks to the high fill power and baffled construction. It handles cold dry conditions well but is not a parka substitute in extreme cold.
Is the Magma 850 waterproof?
No. The shell resists light moisture but the down is not treated as waterproof, so pair it with a rain shell in wet weather.
Does it pack into its own pocket?
Yes, it stuffs into a pocket for compact storage in a pack.
What sizes are available?
It comes in regular, big and tall sizing, and a hooded version is also offered.
How should I wash it?
Machine wash cold with down-specific detergent, then tumble dry low with dryer balls to restore loft.
Is it good for backpacking?
Yes. Its low weight and small packed size make it a common choice for three-season backpacking.
Where is the REI Magma 850 Down Jacket cheapest?
At REI, for $239.00, as of our latest check.
