REI Co-op - Magma 30

Did you get the new magma 15? I got each the 30 and the 15 and while I love them, I feel like there’s such a huge gap in temp conditions. The 15 I’ve slept in down to about 22 and it was WAY too warm still. If I slept in the 30 down to 22 I’d undoubtedly be cold. I just think it’s bizarre they came out with two bags that seemingly have a huge gap.

I got an REI Magma 30 on sale last year for like $230. I absolutely love it and it weighs in at least than 1.5 pounds. I haven't really tested the limits of the quilt by itself, but it's definitely warm enough to wear lightweight sleep clothes down to about 40F. With warmer base layers I could probably nudge it down to freezing.

I have an older REI Half Dome 2+ that I love. It's (barely) light enough for short backpacking trips, spacious enough that I have room to spread out when car camping, but not so big that it's a hassle to set up or put away. I camp in it by myself, but it's big enough my husband or a friend could share it with me and we wouldn't feel cramped (a lot of "2-person" tents have dimensions that, unless you're full-on snuggling all night, are not going to be at all comfortable for two to share). I'm also a quilt convert. I have to be able to kick a leg out when I'm sleeping, and traditional sleeping bags are usually too constrictive for me. I have an REI Magma 30 quilt and I really like it. You're going to want to try on backpacks in person so you can be sure the harness and hip belt work for you. They're all a little different so recommendations are hard to make. That being said, I'm extremely happy with my Gregory Deva 60. It's ridiculously heavy (well over 4.5 pounds) but fits so well I forget I'm wearing it. The hip belt works so well with my body that I can lift the load completely off my shoulders and carry all the weight on my hips if I want. If you don't have to get this stuff right away, sign up to be an REI member and wait a few weeks. They have a big members-only sale in March, and their biggest sale of the year is around Memorial Day. You'll also have access to REI Resupply where they sell used equipment. You can get some crazy good deals on barely-used gear there.

REI magma 30. It’s down so packs small and it’s <$400. If you have a larger budget, go with the other posters recommendation.

Seconding this one. I just got one this year and really like it.

Go with the REI Magma 30, it's ultralight, packs small, and perfect for 45°F with an underquilt. It's 329 on rei official website. Many reviewers highlight how it’s easy to vent or cinch, works great as both a quilt and a blanket, and is ideal for backpacking or hammock setups. On the other hand, you coulld also take a look at NEMO Disco 15, maybe an overkill for 45°F but insanely comfy and reliable — great long-term buy if you value warmth and durability over pack size. FWIW, I recently did an analysis on Reddit data for sleeping pads. Basically ranked them by aggregated sentiment. Maybe you'll find it helpful [https://redditrecs.com/sleeping-pad/](https://redditrecs.com/sleeping-pad/) You can filter and get a breakdown of what ppl have said about the most often recommended ones (disclaimer some links are affiliate they help fund the analyses)

Three seasons where exactly? A better question may be will your trips ever have nights below freezing? You did say "at least..." so I imagine yes? If so, I'd look at the REI Magma 15. If not, try the Magma 30, or Magma quilt. There are plenty more options from really good companies, but since this is a REI subreddit, I thought I'd mention them. Make sure you have a good, warm sleeping pad. And I'm a fan of liners. Keeps the bag clean, and add some warmth too.

Its pretty shocking how heavy TNF and other brand 2 person tents are, 4, 5 and 6 lbs usually. Once you hit that 2 LB or so mark...holy crap...its a whole new world. Same for dumping my heavy 0 degree down bags for 15 and 30s. POOF...there goes another 1.5 lbs at least. The backpack empty weight is a hard one. I have a couple TNF Prophets I like. they're sturdy enough for 65 Liter capacity and only about 3 lbs. Most 65L packs however are in the 4-6 lbs range empty. I tried a Crown 60 and didn't have a great time with it. I should try it again since I think some other factors added to the misery (rain, shoes weren't great, too much fishing gear). I'll also shill for Facebook Marketplace: You'd be shocked at how many people are moving in and out of your area, giving up the hobbies they have and you can get a pretty good deal on nice equipment if you're polite and actually show up to buy it. Both my Big Agnes tents were acquired that way and I'm so glad I snagged them at about 50% off barely used.

Its not the new one. When REI had their clear out of the model they've been selling the last few years, I bought 3 30s and one of the 15s. Got them for under 80 or so each.

30 for lower elevations summer...15 for high elevation for me every time.

I just got the magma 30 and would recommend. Compact, lightweight, and very cozy.

Second the Magma 30 quilt. Incredibly small, light and ive never gotten cold with it (until I took it out into freezing temps, which is on me).

I bought the REI Magma 30 quilt in a large, where I would usually buy a medium. It has a sewn footbox. As a side sleeper, with the extra length and width, it works excellent for those warmer nights as it's long enough I don't have to put my feet in the box. Also, I lay the top out flat when I get warm and cinch up the upper when it's cold. I'm sure this is no real revelation for many, but OP may appreciate the versatility. For me, I've slept in it down to 30 with light weight base layers, and have found I can stay comfortable up to high 60s. Humidity does impact that upper end comfort.

Many disagree, but I love my REI Magma 30 Quilt

Magma 30 is pretty good. Make sure you have a good sleeping pad, r value of at least 3.

I would definitely recommend a warmer bag, especially if you are in Canada, like maybe 20-30 degrees. I have a mummy bag but it's a bit oversized (REI) so I can move around a bit more.

Featherstone tent, REI sleeping bag from their used gear section. Edit: took a WELL used featherstone granite 2p tent on the Great Divide Bikepacking route. 69 consecutive nights of use in all types of weather. Rain, snow, high winds. It was Bombproof. It still had tons of life left at the end. Picked up a used REI magma sleeping bag from their used gear section and used it for 60 consecutive nights of bike touring in South America. I still have it and it still works great.

If you want light weight, small packed size and good temp rating… the magma by REI is the best bang for the buck… because of the size choices. If that is to much… The Trailmade is super inexpensive, and comes in a variety of lengths and widths. It is not as light, nor as compactable. If you were in the store, I would ask a whole bunch of questions… side, back or stomach sleeper? Do you roll? Where do you normally get cold? What is the likelihood of the bag getting wet? Etc… etc… I’d ask because there are so many options and each kind of sleeper works with a different kind of bag. But if you want the lightest and most compact… and best bang for the buck… the magma is the way to go? also do not forget to buy or make a liner. No sleeping back should be used without one!

My advice: NEMO women's Disco 15. First off, sleeping bag temps (ISO/EN) are rated for slight discomfort. If you want to be mostly comfortable at 30F, you get a 30F bag; if you want to be warm and toasty, you get a 20F bag. If you think temps may drop into the 20s but may realistically be 30s, you should get a 20F bag; if it hits 20F, you're fine but you'll otherwise be toasty. Women's bags are rated at the Comfort rating which is toasty and nice for a warm sleeper, slightly uncomfortable for a cold sleeper - which is the assumption for women. Also what it sounds like you may be: a "cold sleeper"/someone who likes to be warm at night. Know that you can - and should - try other gender bags for fit as you may find better fits across genders. But keep in mind there is ~10F temp difference between men's fits and women's fits (men's will be colder for cold sleepers, women's will be warmer for warm sleepers) and so don't just trade 30F for 30F. In your case, use the "Comfort Rating" as your slight discomfort temperature and adjust from there. Know also that this may work against you price-wise; they do not price based on fill, they price based on advertised temp. So a women's 30 will be the same warmth as a men's 20, but will be priced as a 30, not as a more expensive 20. So the Magma and the Disco may not be warm enough for what you're looking for. Of the listed bags, they'll fit in order of how you listed them: Disco will be the widest, then Big Agnes, then the Magma. The Magma is a true backpacking mummy and won't be ideal for a side sleeper. The Disco has extra space in the shoulders and hips which are ideal for getting on your side in the bag. So for a cold sleeper who sleeps on their side and is likely to have some 20F but maybe mostly 30F nights - NEMO Disco 15. Should check all of the boxes. The one big difference between the NEMO and the Magma is down fill power, which also impacts compressibility and weight. Magma is an 850 while the Disco is probably around 650-700. If you want a similar fill power bag go with the Riff 15. 850 fill down also warms up quicker because the feathers are smaller. It will also probably be more on par price-wise with the Magma. The Riff has all the same features as the Disco though may have a slightly slimmer shape. If you can, go to your local REI and get in each one to see which are comfortable and which are not. But based on the info you've given, I'd suggest either a Women's NEMO Disco 15 or NEMO Riff 15.

Remember that you can move your legs around all you like by moving the sleeping bag with them. I sleep in the fetal position in a very narrow bag because I curl the bag into that position with me. (I have REI's magma and it's extremely toasty)

I like the REI Magma

Try a quilt. I recommend the sierra designs 20(?) or rei magma

I have also gone to ground. I took my quilt with me and love it. I have used a sleeping bag, and it just isn’t as nice. My quilt is the Warbonnet Diamondback, and my sleeping bag is the REI Magma. I have never had cold sleeping problems, I just enjoy the quilt more.

I went with the Magma and a Nemo Tensor wide sleeping pad. Thanks for the recommendation

The REI Magma mens/women's bags zip together and are wonderful. They have both 15⁰ and 30⁰ bags.

Interestingly, I hated my Magma. I don’t feel it performed as well as advertised. Got an Enlightened Equipment quilt and have been much warmer.

My order of preference, without prying more info out of you would be: 1. Magma 2. Radiant 3. Nemo … anyone giving you numbers after the name of the bag is guessing because you never mentioned what temperature rating you need and what geography we are talking about. In terms of r-rating we would need to know what mattress pad you are shlepping too…
