REI Co-op - Magma 30

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.

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.

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.

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

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!

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)

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.

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…
