REI Co-op 650 Down Jacket Review

Overview

The REI Co-op 650 Down Jacket is a no-frills, hoodless puffy built around 650-fill-power down and a windproof recycled nylon shell. At $129 list, and frequently half that when REI runs sales, it is one of the cheapest ways into a down layer. The trade-off is plain: at 309 g it is neither especially light nor especially warm for what it weighs, so it fits casual and shoulder-season use better than a gram-counted thru-hiking kit.

Performance

Warmth. The 650 fill is modest by current standards, and testers say so. Outdoor Gear Lab’s reviewers put it among the lowest fill powers in their down-jacket lineup, but found that the generous fill kept them warmer than expected, even as they stopped short of calling it a warm jacket. Better Trail’s tester rated warmth just 2.5 out of 5 and advised keeping it for temperatures around 45°F and up. Owners’ descriptions are consistent with that: very light and warm for cool evenings, trailhead mornings and camp. Nobody is describing it as a winter belay jacket. The men’s tag has been reported to read “Down (80% Minimum)”, so the fill is a down-and-feather blend rather than pure down, which is common at this price but worth knowing.

Weight and packability. At 309 g, the jacket is about the weight of a basic synthetic midlayer and well above premium down sweaters built on 10D fabrics. Better Trail’s tester noted the shell feels more substantial than ultralight designs like the Mountain Hardwear Ghost Whisperer and closer to the Patagonia Down Sweater. That extra fabric helps durability and costs grams. The jacket compresses well enough for a pack or a full suitcase, and buyers disagree on the stuff-pocket: one calls it a non-issue because they jam the jacket into a pack gap or compression bag anyway, while another reports it folds into its own pocket without trouble. Thru-hikers who want a tidy, defined stuff sack will want to bring their own.

Comfort and fit. This is where the jacket overperforms. Outdoor Gear Lab testers called it plush for the price, with a lining as soft as jackets costing more than twice as much, and said it fit all of their testers. Better Trail rated comfort 4.5 out of 5. The cut is boxy and slightly cropped, which layers easily over a fleece but also means reaching overhead can lift the hem and cuffs. Reviewers of the women’s version noted that the short torso and lack of underarm gussets expose wrists and waist when stretching. The men’s Tall option adds two inches of back length for longer torsos.

Weather resistance. The shell is wind-resistant and sheds snow and light rain, but the DWR is the PFAS-free sort and does not match premium finishes, according to Better Trail. One buyer who took it to Iceland found it fine in light rain and not something to trust in a downpour. Treat it as a dry-conditions layer.

Durability. The fabric is not tough. Owners report snags on chicken wire and fences, and a chain-link fence tore a large hole in a previous-generation jacket belonging to one Better Trail tester. REI’s repair patches fix such damage, and some owners wear the result with pride, but off-trail bushwhacking is a poor use for it. A smaller group of reviewers flagged sewing flaws, and the women’s version’s reviewers noted feather leakage on some jackets. Reported satisfaction is high regardless: 4.4 out of 5 stars across 485 men’s reviews on REI.com.

Pros & Cons

Pros

• Very low price, with 50%-off sales common
• Soft, comfortable lining and easy layering over a fleece
• Windproof shell with PFAS-free DWR
• Four pockets, plus hem drawcord and bound cuffs
• Tall sizing available for longer torsos

Cons

• 309 g is heavy for the warmth delivered
• 650-fill down blend loses loft sooner than higher-quality fill
• No hood
• Shell snags and tears easily
• Boxy, cropped cut rides up when reaching
• Not suited to cold temperatures

Who Should Buy This

The ideal buyer is a weekend hiker, car camper or traveler who wants one inexpensive down layer for town, trailhead and camp in mild to cool weather. It also works for a first-time backpacker who does not yet know how much warmth is needed. Thru-hikers and ultralight backpackers building a cold-weather system should look to jackets with higher fill power, a hood and lighter fabrics. Anyone heading for sustained sub-freezing temperatures should skip it.

Verdict

The 650 Down Jacket is a comfortable, honest, inexpensive puffy that does what a casual layer should. It is not an ultralight piece, and its modest warmth and delicate shell limit it on serious trips. Buy it on sale for everyday and mild-weather hiking; pay more for hiking in the cold.
