Our Verdict

The REI Co-op Igneo 17 is a reasonable, quality bag that offers a performance level that is almost on par with much costlier bags, such as the Western Mountaineering MegaLite or the Western Mountaineering UltraLite. The Igneo crosses over into the higher-end bag categorization while keeping its middle-of-the-road price, which as about a third of that of its peers. It offers decent quality 700-fill water-resistant duck down, along with one of the nicer shell fabrics in our review. Its dimensions on the smaller side, but we wouldn't consider it super tight fitting. Those that are used to mummy bags won't find it much smaller than average among higher-performance bags. All that said, we still think the Western Mountaineering UltraLite is a nicer bag, as it offers higher-quality down and a lower weight shell, which creates a warmer and more compressible bag - for the same weight.

Update - April 2017
The Igneo 17 is the completely redesigned model of the Igneo, which we reviewed. Rei enlargened the foot box to make room for natural foot splay and reduced the size of the shoulder circumference to better fit female users. To learn more about these changes, among a few others, scroll down.

New Igneo 17 vs. The Old Version


REI updated the Igneo for spring 2017. The latest version features an updated foot box, which is constructed to be larger to accommodate for natural foot splay. The shoulder circumference is also been reduced, with the ladies in mind. The bag is rated to be warmer, dropping a few degrees off its lower limit, from 19 degrees Fahrenheit to 17 degrees Fahrenheit. Long and wide sizes have been added to the purchasing options for the Igneo, and the list price remains consistent. You can spot the new model by its new, Vin Rogue color.

Check out the side-by-side comparison below, with the latest version, the Igneo 17, pictured on the left and the older version shown on the right.

Here's a full summary of the updates:
  • Foot Box Circumference — According to REI, "Feedback from across the co-op was used to improve the comfort of the foot box, making it larger to accommodate natural foot splay."
  • Shoulder Girth — REI reduced the size of the shoulder circumference to better fit female users.
  • Color Update — The latest model has done a color one-eighty, from light gray to a wine-tinged red.
  • Temperature Rating — The new model has a lower limit of 17 degrees Fahrenheit and a comfort rating of 28, which is two degrees lower than that of the old model.
  • Weight — The new model has a weight of 1 lbs. 15oz (compared with 1 lbs. 13 oz).

We haven't had the opportunity to test out this new version of the Igneo yet, so the main review text and ratings reflect that of the Igneo.

Hands-on Review of the Igneo


The REI Igneo is a fantastic value for a 20F sleeping bag using fairly high quality materials and a solid design to create a very light and pack-able $300 sleeping bag.

Warmth


One of the warmer bags in our review, the REI Igneo is rated to 20F and uses 15 ounces of water resistant 700+ fill-power Duck down for insulation. In our real-world testing, we found that this contender was accurately rated. Our review team found it to be on the warmer side among 20F bags we tested; it provided itself to be a warmer option in a direct side-by-side comparison, beating out the Kelty Cosmic Down and The North Face Cat's Meow. The Igneo isn't quite as warm as the comparably rated Western Mountaineering UltraLite (20F), which features one more ounce of slightly higher quality down (16 ounces of 850+ fill goose down). While one ounce may not seem significant, the UltraLite was noticeably warmer.

The REI Igneo was one of the warmer sleeping bags in our review. While it wasn't quite as warm as the similarly rated Western Mountaineering UltraLite  in our side-by-side testing it was warmer than The North Face Cats Meow or the Kelty Cosmic Down.

Weight


The REI Igneo weighs in at 1 lb 13 oz; this is pretty darn light for a bag that's as warm as this contender. It's on the lighter side of comparably rated bags and is nearly half the weight of the similarly rated 3-pound Kelty Tuck 20. It's lighter than the Kelty Cosmic Down ( 2 lbs 13 oz), or The North Face Cat's Meow (2 lbs 11 oz) and weighs the same as the Western Mountaineering UltraLite; however, the UltraLite is noticeably warmer. The 700 fill-power down the Igneo uses a mid-range quality of down, but features a light, down proof, high-quality shell fabric that feels nice against our skin.

The REI Igneo packs down smaller-than-average among comparably rated models. However its included stuff sack did an only okay job of compressing it and buy and aftermarket compression stack will help you pack the Igneo around a third smaller.

Packed Size


This contender packs down smaller than average and offers one of the better packed sizes among 20-25F bags in our review. It doesn't pack down quite as small as its' closest competitor, the Western Mountaineering Ultralite, Marmot Hydrogen, or the Sea to Summit Spark III. It does however, pack down much smaller than bags that aren't quite as warm, like the Mountain Hardwear Hyperlamina Spark 35 or the Kelty Cosmic Down 20.

The REI Igneo packs down fairly well  but you wouldn't know it in its over-sized included stuff-sack; pictured here on the second from the right.

Comfort, Spaciousness, and Fit


This bag features a 60" wide shoulder girth and 55" hip girth. This is slightly on the slender side, but hardly extreme. All of our testers noticed that this contender felt tighter around the legs. Folks who like to move around a lot or sleep on their tummy stand a higher chance of finding this bag to be too tight fitting. While it offered more space than the Sea to Summit Spark III or the Western Mountaineering Ultralite, it felt pretty comparable, though a little smaller that the Marmot Hydrogen. The Igneo wasn't even close to as spacious as the Nemo Salsa 30 or the the Western Mountaineering MegaLite, which offered a noticeable amount of additional room that we used to wiggle our legs around in.

The REI Igneo (Center) offers ample shoulder space  and was still wider than the Sea to Summit Spark III (left)  but tcompared with most performance oriented mummy-style bags he Igneo's design tappers more than most from your hips to your feet and most of our tummy sleepers didn't like the Igneo as much as other options.

Versatility


This bag is quite versatile; its' fit is slightly on the snug side, but still decent for most folks that will use this bag for car camping. It's also light enough for most backpacking trips of any length. Its' full-length zipper helps keep it comfortable on warmer nights, but its torso/shoulder area is big enough to accommodate extra layers for a person of any size.

Our testing team dug the cool pattern on the soft and cozy feeling internal fabric of the REI Igneo.

Features and design


This contender uses water-resistant down that is created by blending a polymer-coated down-fill. During OutdoorGearLab's spray bottle test, REI's polymer treated down did appear to absorb slightly less water than an untreated similar fill-power sample; this light amount of moisture dried roughly 25% faster. We also performed a "full soaking test", where we noticed less visible difference between the two. In our review teams' real world testing (where we never actually completely soaked the bag, just condensation, etc.), we noticed even less of a difference. We think that REI's (and other) polymer-coated down is marginally more water resistant and potentially offers slightly quicker drying times, but not by a considerable amount.

The nylon shell of the Igneo is one of the more water-resistant options we tested. Lastly, all of our testers dug the cool internal materials' pattern.

We think the REI Igneo is a pretty solid all-purpose bag. Some folks might find its lower dimensions a little tight for car camping  but for most other applications the Igneo excels for casual or long range backpacking  summer-time mountaineering or even spring ski touring.

Best Applications


The Igneo is a pretty solid all-around bag. It's light enough for most backpacking trips from overnight, to multi-week adventures, is comfortable enough for occasional car camping, and is still warm and packable enough for spring and summer mountaineering trips.

The REI Igneo offers a full length zipper that snagged the least amount of any bag we tested.

Value and the Bottom Line


The REI Igneo is an above-average sleeping bag, at a very reasonable price. It's one of the lighter and more compressible bags of its temperature rating, offering solid warmth, and a cozy interior fabric. We think it's comparable to the similarly priced Marmot Hydrogen, we'd buy the Hydrogen for most backpacking trips, as it's a little lighter and more packable. However, the Hydrogen is also only rated to 30F. We'd consider the Igneo if we had a colder sleeping temperature; it would also be useful if we wanted a bag that would be used for more trips in the shoulder seasons, or at higher elevations when the Hydrogen might not cut it warmth-wise.
