Our Take:

Certified

The REI Co-op Magma 850 Down Hoodie ($259) strikes an appealing balance between comfort, insulation, and durability at a price that undercuts many premium competitors. It isn’t the lightest puffy on the market, but its extra heft comes with dependable warmth and a confidence-inspiring build that works just as well around camp as it does in town. For shoulder-season backpacking, casual cold-weather use, and anyone looking for a versatile down jacket, the Magma 850 is an easy, high-value recommendation.

Pros

Impressive materials, features, and performance given its price point.
Packs down into its own pocket, small enough to take on backpacking trips.
Includes thoughtful touches, like an adjustable hem and hood and a draft flap.

Cons

Might fall into a middle-ground use-wise, as it’s neither very light nor very warm.
Updated, trimmer fit might be harder to fit over other layers, depending on body shape.

I was pleasantly surprised by how warm the REI Co-op Magma 850 Down Hoodie felt, given its low price (for a jacket with 850-fill down) and its relatively unobtrusive look. REI doesn’t provide a fill weight for this jacket, but in terms of loft and warmth-to-weight ratio, 850-fill down is right up there with the insulation used in some of the category’s top models. It’s not an ultralight piece, but it’s not an overbuilt belay parka, either. The Magma is noticeably warmer than featherweight options like the Arc’teryx Cerium and the Himali Accelerator, but bulkier classics like the Rab Microlight Alpine and the Patagonia Down Sweater are toastier.


I wore this jacket in temperatures ranging from the low 30s to the mid-40s with a midweight sweater underneath and stayed comfortable while standing around camp and during light activity. On an October trip to Malachite Lake in Washington's Alpine Lakes Wilderness, it was exactly what I wanted once the sun dropped below the horizon. The Magama’s loft and heat retention feel appropriate for its specs, and features like the main zipper’s draft flap help conserve heat. I wouldn’t pack the REI Co-op Magma 850 Down Hoodie as a standalone puffy for winter conditions, but for normal three-season use, it lands in an adaptable sweet spot.

At 12.5 ounces, the Magma 850 is heavier than many minimalist down jackets, like the Rab Mythic G (9.8 oz.), but that weight never felt like a drawback during testing. It carries well when you’re wearing it and doesn’t feel cumbersome when stashed away. As I mentioned, it’s not an ultralight piece; for comparison, it’s heavier than the REI Co-op 650 Down Hoodie (11.6 oz.) and the Stio Pinion (12 oz.), but lighter than the Cotopaxi Fuego Hooded (13 oz.) and the Patagonia Down Sweater Hoody (14.8 oz.). It’s a touch warmer than all of those models, though, save for the Down Sweater.


The Magma packs into its own pocket and compresses to a flat, rectangular shape (much like a large novel) rather than a ball, making it easy to slide into the shove-it pocket of my Gregory Baltoro backpack. That flatter packed shape is an underrated advantage, especially for longer trips where space is at a premium and oddly shaped items can be hard to fit. While I wouldn’t choose this jacket for an ultralight kit where every ounce matters, I’d happily bring it on most backpacking adventures, where the slightly heavier build and relatively robust face fabric make it feel better suited to real backcountry use than some fragile ultralight puffies.

The Magma 850 is a comfortable, well-tailored jacket that doesn’t restrict movement. I’m 5-foot-9 and 155 pounds and tested a men’s small; the sleeve length was spot-on, and the jacket moved naturally with my shoulders and arms. The hood fit comfortably over a beanie or low-profile ball cap and still allowed good head mobility even when worn over a helmet.


The Magma 850’s nylon face fabric feels soft, though not the softest I’ve worn. Jackets like REI’s 650 Down or the Mountain Hardwear Stretchdown feel more plush against the skin, but the Magma’s designers seemed to prioritize durability and cost control over a luxurious handfeel. I’m not complaining, though: When I pulled the jacket on at camp, it felt reassuring in a way that lighter jackets sometimes don’t. It isn’t particularly breathable, and there are no venting options, but that’s typical for a down puffy in this category.

The REI Co-op Magma 850 Down Hoodie feels like a dependable, everyday down jacket rather than a delicate specialist piece. REI doesn’t list a denier rating, but in hand, the nylon face fabric feels moderate in thickness, not paper-thin like the Mythic G, but not armor-like like the Stretchdown’s material. I was comfortable wearing it around camp and town without constantly worrying about brushing against branches or gear.


The zippers are smooth and confidence-inspiring, and when testing it alongside the La Sportiva Lumina 200—an expensive ($379) ultralight puffy that feels much less robust—I consistently reached for the Magma and left the lighter jacket in my closet. The Magma felt both tougher and more forgiving in how I could treat it; it’s the kind of jacket you grab when you’re heading out the door in a hurry and don’t want to baby your insulation.

This isn’t a waterproof jacket, but it does offer some light weather protection. In mist and brief drizzles, water beaded on the face fabric’s surface and rolled off without immediately soaking through. REI uses a PFAS-free durable water-repellent finish on the Magma’s nylon, and the down itself is treated to resist moisture, which adds a layer of reassurance.


That said, moderately sustained rain or wet snow will overwhelm it—that’s not a knock on its design, it’s just par for the course for even DWR-treated down puffies. In those conditions, I’d always pair the Magma with a shell or opt for a synthetic insulated jacket instead. Incidental moisture like morning dew or a quick sprinkle while you’re hiking shouldn’t be an issue, though.

Longevity

Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.

The Magma’s feature set is straightforward but well executed. Its hood is adjustable and sized generously enough to work over a helmet, though the fit is a bit snug in that configuration. The jacket includes two zippered hand pockets and a zippered chest pocket, all of which are easy to access and sized to hold an iPhone or a couple of energy bars. Finally, the internal draft flap behind the zipper did a good job sealing in warmth and adding to the Magma’s cozy feel.

Tester: 5’9” 155 lb.

Size tested: Men’s small

I typically fall between a small and a medium when it comes to down jackets, and the small worked well for me, especially in the shoulders and arms. The Magma’s fit felt modern and trim without being restrictive; the torso has enough room to layer underneath without feeling boxy; and the current version is noticeably trimmer than older models of this jacket. It also layers cleanly under a rain shell, which adds to the Magma’s versatility as a midlayer.

REI Co-op 650 Down Hoodie ($149): Save Even More Money
The Magma may present good value for a jacket stuffed with 850-fill down, but the 650 Down Hoodie is a fantastic deal, full stop. It’s half the price but comfortable and fashionable, with a cropped cut that might make it even more appealing for wear around town. The 650’s down is less lofty and compressible, but it still packs down small enough for backpacking, and it’s even lighter than the Magma at 11.6 ounces. However, the 650 is less warm, and you’ll have to bolster it with other layers when temperatures hit around 40 degrees (what’s more, the hooded version is only available for men). Its DWR is also less effective than the Magma’s, and it’s not as durable. At this price, though, you might consider snapping it up just as a good-looking backup. To learn more, check out our 650 Down Jacket review.


Arc’teryx Cerium Hoody ($400): A Category Standout
The Cerium also features 850-fill down, but it costs quite a bit more than the Magma. The reason? It’s better suited for technical missions such as climbing or fastpacking, with an even trimmer fit and better warmth-to-weight ratio via a thinner face fabric and more insulation. However, the Cerium’s 15-denier nylon won’t handle as much rough-and-tumble use, and it’s slim enough that layering under it is difficult, making it less than ideal as an everyday piece. The Magma is more versatile, but the Cerium is better for testing your limits in the mountains. For more, read our review of the Cerium Hoody.

The REI Co-op Magma 850 Down offers premium 850-fill warmth, solid durability, and a performance fit at a price that undercuts many competitors. While it’s slightly heavier than true ultralight puffies, it makes up for it with better comfort, toughness, and all-around usability.

For just $149, REI’s 650 offers incredible value for those looking for a casual down jacket that can tackle the odd mild-weathered backcountry adventure. However, you won’t want to push it into too cold of temperatures, the DWR is disappointing, and the boxy fit isn’t for everyone (although our tester actually liked it).

The Cerium offers extremely lightweight and packable warmth for technical pursuits like alpine climbing and backcountry skiing. Its streamlined fit is ideal for layering, too. However, given the price point, thin fabrics, and trim fit, we don’t recommend this jacket for everyday use.

Is the Magma 850 for You?

If you’re in the market for a medium-weight down jacket that works for three-season backpacking, camping, and around town, but that’s more versatile and cheaper than a technical puffy, the REI Co-op Magma 850 Down Hoodie should be on your radar. It’s neither the lightest nor the warmest puffy we’ve tested, but it’s comfortable and feels reliable rather than fragile. We’d look elsewhere for ultralight missions or use in consistently wet climates, but for daily cold-weather use, the Magma 850 will work well.
