REI Magma Trail Quilt 30 Review

REI Magma Trail Quilt 30 Review

The REI Magma Trail Quilt 30 is a lightweight alternative to a mummy sleeping bag, weighing just 19 oz. It’s insulated with 850 fill power goose down and rated for temperatures down to 30 degrees. The Magma Trail Quilt 30 saves weight because it doesn’t have a hood, a zipper, or a back like a sleeping bag, chopping 10 or more ounces of weight compared to a similarly rated sleeping bag.

Besides reduced weight, many people find sleeping under a quilt to be more comfortable than a sleeping bag, because it’s less confining and more easily vented. It’s easier to sleep on your side because you’re not constrained by a mummy hood and you can pull a quilt back like a blanket if you’re too hot at night. You can also get in and out on the right or left sides, since the quilt doesn’t have a zipper.

The REI Magma Trail Quilt 30 isn’t fully enclosed in back but hugs the sides of your sleeping bag to prevent drafts from blowing up under the sides and chilling you. It’s held in place by a pair of sleeping pad cords that attach to the quilt’s sides with plastic dowels that slip through loops sewn in the quilt. It takes a little practice getting used to these cords (called a pad attachment system), getting into the quilt  or detaching one side so you can get in and out at night.

There are three positions on the quilt where you can attach the sleeping pad cords: the two shown above and or at the top of the quilt, just below the collar. The collar closes with a snap in the back. This pulls the sides of the quilt together, so you don’t need a cord there. But it’s something you may want to experiment with. Quilts do require practice and some adjustment to get used to, unlike sleeping bags which are pretty idiot-proof. Do yourself a favor and take the REI Magma Trail 30 Quilt on a shakedown test trip close to home before you bet the farm on it.

In warm weather, you can often just drape the quilt over your pad like a blanket and ignore the pad attachment system. But when it gets cooler, you’ll want the quilt’s sides locked in place over the sides of your sleeping pad. I find this is easier to do with a reasonably thick inflatable sleeping pad like a Therm-a-Rest NeoAir but quilts are compatible with self-inflating and foam sleeping pads as well, provided they have solid backs for insulation.

The Magma Trail 30 has a trapezoidal footbox like most sleeping bags to keep your feet warm. It’s not vented at the end with a drawstring but fully enclosed. It can be used in two ways: you can slide your sleeping pad into the foot box if you have enough room under it for your feet to fit, or you can put your feet in the footbox and lay them on top of the quilt. If you do the latter, the weight of your legs will keep the top sides of the footbox flush with your sleeping pad so drafts can’t sneak in. Whichever way you choose is a matter of personal preference. I normally keep mine on top, for what it’s worth.

While you can buy a quilt with a vented footbox that closes with a drawstring, it’s a nice-to-have in warm weather but not a necessity. It’s just as easy to kick your feet out the sides if you’re too warm. Using a quilt is similar to sleeping under a blanket or a duvet in this respect.

The REI Magma Trail Quilt has a feature called a draft collar, which I consider far more important on a quilt than a vented foot box. This is a down-filled collar that wraps around your neck, insulating the blood flow there, and blocking any heat from escaping out the top. It’s the puffy orange tube, wrapped around my neck above. The collar is tightened using a drawstring at the top of your chest, which makes it very easy to adjust while you’re in/under the quilt.

While the Magma Trail 30 is lighter weight than a comparable sleeping bag, there’s no such thing as a free lunch. Sleeping with a backpacking quilt is less fool-proof than using a sleeping because you’re not fully enclosed by draft-proof fabric. The quilt’s 30 degree temperature rating requires that you use a warm sleeping pad (an R-value of 4 or more is recommended), you wear long underwear, socks. and a fleece hat or down hood (See backpacking quilt temperature ratings). I’ve slept with the Magma Trail 30 Quilt down to 25 degrees this way and believe its temperature rating is conservatively rated by REI.

The REI Magma Trail Quilt 30 is available in three lengths that fit people up to 66″ (short),  regular (72″), or long (78″) in height. When sizing the quilt, it’s best to pick the length that corresponds best to your height, sizing up if you fall in between two sizes. Don’t try to size down to save gear weight.

The Magma Trail Quilt is generously sized with shoulder / hip / footbox dimensions of 56″ / 52″ / 44″. The 56″ shoulder girth will fit most adults with a regular sized torso or those packing a few extra pounds. The footbox is sized for large feet up to about size 13-14, although how much room you experience will depend on whether you insert your sleeping pad into the footbox or on top of it instead. The footbox is also large enough to work with both 25″ and 20″ wide sleeping pads.

The REI Magma Trail Quilt 30 is a quality backpacking quilt insulated with 850 fill power water-resistant goose down, a silky liner fabric, and a Pertex Quantum exterior shell. It has an easy-to-use pad attachment system if you’re sleeping on the ground, which can also be easily removed if you want to use it as a hammock top quilt. I think the Magma Trail Quilt 30 is a great value and it’s nice to see REI getting behind quilts to educate the market and provide more options for their members.

Of course, the nice thing about buying a quilt from REI is that you can try it and return it if you decide that a quilt is not for you. If that’s the case, I’d encourage you to consider a quilt-style sleeping bag instead. These are hoodless sleeping bags with a full-length zipper that provide the same venting and the weight savings of a quilt, but provide the draft protection of a regular sleeping bag. They’re quite comparable in weight to backpacking quilts, but easier to use. (See Quilt-Style Sleeping Bags: Pros and Cons for more information.)

  1. I’m trying out a quilt for the first time this season in Colorado high country, and went with this one for all the reasons mentioned in this review. So far, I’m loving it! I’ve now spent about a dozen nights under it in a variety of temps, from warm nights to light frost at 11,000′. Wet nights and dry. It’s very versatile and comfortable in a range of conditions.

    Perhaps the thing I like about it most versus my sleeping bag is not just the weight savings but the pack size. I discipline myself to a 45L pack, so space is a premium for longer trips.

    I’m a cold sleeper, so I couple it with a NeoAir XTherm, Thermarest’s warmest pad at R6.9. So far, no cold nights, in contrast with my old bag. I dress similar to the reviewer and have a down puffy nearby for that extra something.

    I agree the fastners take some getting used to, especially with cold fingers, but I am getting them down, and I think the loops on the quilt stretch just a bit over time, which make them easier to fasten.

  2. Just picked this up a couple weeks ago with the recent REI coupon and used it last weekend in temps down to mid 30’s. Was my first time using a quilt and definitely proved to be more comfortable turning from side to side. While it did get a bit chilly, I ended up putting on my puffy to answer a nature call and opted to leave the puffy on rather than take the puffy off and try out the snap and draft collar all cinched up. I stayed warm through the rest of the morning thereafter. I’ve noted some reviews and comments elsewhere, including yours above mention that this quilt has sewn-through seams. I don’t find that to be the case with mine. I can grab the seams along most of the baffles from the outside and inside and pull them apart as well as rub them together and across each other. It definitely feels like there’s about an inch wide strip of fabric sewn between the baffle seams to create more of a boxed baffle. Maybe that’s something that was just recently updated this year? Definitely doesn’t feel sewn through at all.

    Still, I’m contemplating returning it in favor of a UGQ Bandit of the same rating with some overstuffing and the dynamic tension control along the edges and easier to use wafer clip strap system available through them. Yes it’d cost me about $100 more when factoring in the coupon I had with REI. It will also be a few ounces more in weight, but I think I could be more confident in being able to take it down to mid-20’s for full 3 season use in the areas I typically go with my X-lite, base layers, down puffy, and even down balaclava I have. I’d also get it with the insulated footbox too. The REI quilt has wider baffles and when I hold it up to light, there are definitely spots where the down drops away from the seams showing where some potential cold spots could develop despite what feels like boxed seams for the baffles. I also like that the UGQ has some snaps above the footbox when getting a sewn footbox that allow you to close it up more for those colder nights. I had my wife watch me twist and turn with the REI quilt pulled in pretty good under me with the straps on my pad and the upper footbox was the only spot that was lifting up to expose significant draft points. I think with the extra snaps the UGQ comes with along with the DTCS added to it would eliminate all that. However, if I do end up committing to keeping the REI quilt, I suppose I could just add my own snaps to it and possibly sewn in a couple extra loops down at the edge of the footbox and thread in some shock cord with cord lock through the loops to try my own dirty version of a dynamic tension system.

    Decisions, decisions….

  3. I just used this on a 2-night trip at Shenandoah NP. Nights (and days) were clear skies, with lows of 35F the first night and 45F the second night; there was. Stiff wind the first night and mild breeze the second night. I was using an REI Helix pad with an r-value of 4.9, sleeping alone inside a double-wall 2-person tent with the vestibule closed the first night and open the second night.

    The first night I slept in long underwear and was comfortable all night. The second night I only needed boxer shorts, t-shirt, and socks. I didn’t use the pad attachment system either night, but did use the neck snap the first night. (It also helps that I don’t move around a lot when I sleep.) I was toasty warm both nights.

    I think this is more of a 40- degree quilt; its listed rating of 30 is not EN-tested (can you test quilts?) However, REI’s Magma 30 sleeping bag (which has about the same amount of fill) is EN-rated at a Comfort of 40F and Extreme of 30F. (Extreme: “You won’t actually die, but your new trail name is Popsicle.”)

    One thing surprised me: I’ve never had a bag or quilt whose foot box kept my feet warm without using insulated booties. In this quilt, my feet stayed warm in dry socks only.

    I’m very impressed with this quilt so far.

  4. I own this and I find it so much better than a sleeping bag in the summer. I sleep warm and this thing is goldilocks for me. I’ve slept with it down to 35°F and was somewhat chilly with wool baselayer, fleece pants, and jacket on an insulated Tensor pad. Its a lightweight summer option for me (White Mountains, NH).

    It’s $329 at REI now, which I feel is in the range of finding a better brand for a similar product. I got mine on sale for $164.50 and I would highly recommend it at that or other severely discounted price. There are some complaints online about the spot where the footbox comes together, its not well reinforced which has led to some folks tearing it, but its simple to fix even preemptively so you don’t tear that area. Mine has not torn in that area and I have not reinforced it (yet). I throw it in a 10L SeatoSummit ultrasil compression sack and it packs down teeny tiny.
