Our premium cold weather bag, the REI Magma sleeping bag features goose down insulation and a waterproof, breathable shell for protection from damp and chilly nights.

Tested by an independent third-party lab using European Norm protocol, the EN temperature ratings allow direct comparisons across brands with other EN-rated bags
Waterproof, breathable shell is an ultralight, coated ripstop nylon designed to dissipate moisture from the inside and repel moisture from the outside, keeping the down dry
800-fill-power goose down is efficiently distributed for maximum warmth and compressibility; ultralight polyester mini-ripstop lining has a soft hand-feel
Exclusive REI Down Fill Calculator optimizes the amount of down per baffle for the most warmth with the least amount of down
60% of insulation is put on top of bag where it contributes the most warmth and loft
In-the-round pattern wraps vertical baffles around perimeter of sleeping bag, from head to foot, creating a 3-dimensional bag that wraps you in warmth
Performance fit saves weight by reducing girth at shoulders, hips and lower legs while increasing thermal efficiency
Baffle spacing is optimized to keep down in place and prevent cold spots
Multichambered contour hood, insulated full-face muffler, and full-length zipper draft tube with ground-level seams all work to keep heat in and cold out
Anatomically contoured draft collar drapes lower in the front and higher in the back for a better fit; cinch adjustable to seal in warmth
Trapezoidal footbox mirrors sleeping position for room to move and thermal efficiency
External chest pocket keeps small essentials—headlamp, watch, glasses—right at hand and easy to find in the dark
Includes nylon stuff sack and large cotton storage bag
Differentiated drawcords (1 round, 1 flat) allow quick identification, even in the dark, so neck and hood adjustments are a cinch
Any REI backpacking bag can be zipped to any other REI backpacking bag because of the consistent 63 in., No. 5, YKK zipper; women's bags zip on the right, men's on the left
Zipper is backed by a wide, welded fabric flap that prevents snagging
Pad loops provide attachment points to keep your sleeping bag and pad together, so you needn't worry about rolling onto the cold ground (straps sold separately)

Imported.

Comments about REI Magma Sleeping Bag:

I'm 6ft, 180lbs and I bought the long. I used this bag during the winter on a backcountry mountaineering trip. Temperatures were in the low 20s and I was as warm as in my own bed at home. I'm a side sleeper and I tend to toss and turn a lot. I didn't have any issues fitting in the bag or moving around during the night. For me, winter trips always mean a lot of time in the horizontal position due to the limited day light. I actually spent 15hrs the first night in this bag and it was tough to get out in the morning!

The bag cinches up very tight around the face to keep all your heat in the bag. I was wearing long underwear, thick shirt, wool socks, and a balaclava and I was perfectly cozy. The stuff sack it came with was adequate for fitting into the sleeping bag compartment of my backpack. The zipper is first class and has no issues with snagging.

The light weight, waterproof fabric, and great warmth is pretty impressive for just one bag. REI gear just continues to get better and better.

Comments about REI Magma Sleeping Bag:

I've been through quite a few sleeping bags and never been satisfied. I'm actually warm in this bag! It is super comfy as well. Funny story - I had the bag shipped to where I thought id be but it was on backorder, so when it arrived i wasn't around for a week or so and it sat at my gate in THE RAIN! When i finally got there the box was soaked, and i was nervous cuz i was planning on using it that night. I opened the box and its "pillow bag" was also soaked - but guess what, to my surprise the bag was %100 dry! It's a perfect shell for the 800 fill down!

Comments about REI Magma Sleeping Bag:

This is a great product if used for right (cold) weather conditions. I used it in Alaska (mountains of Katmai National Park ) this June for about 3 weeks at and above snow line with sub 32 F night temperatures (about 40-45 F inside my tent)- It was too warm for me. So I had to use it almost all unzipped and my feet still felt too hot and sweaty. Almost every night I woke up by being too hot and had to bend knees to provide ventilation. Few night were OK when we were at high elevation and very humid conditions (clouds)with temperature far below freezing. Otherwise this is a great bag- it packs small, has room for boots inside (I am 7'1" and bought Long size), does not absorb moisture from inside and outside, breathable, attractive style and color, feels very fluffy and soft.
One small negative thing- I wish it has a compression stuff bag. It came with a regular stuff bag that is too large for it, so I had to buy a SeaToSummit medium size eVent compression stuff bag for it (an extra $35 cost).
Bottom line- It is a great sleeping bag if used for climbing and/or winter-like conditions. Do not take it with you where sub-season or summer-like conditions are expected- you will be baked alive.

Comments about REI Magma Sleeping Bag:

I recently bought this bag a couple months ago and couldn't be happier with a cold weather bag. I'm very impressed with how light-weight it is and durable. The rip-stop nylon is very strong just from the touch and the fill(how high the bag puffs up to) is thick. What I mean, is when you get into the bag, it expands and makes it look like it's filled with 6" of air around you. No joke, the fill in this bag is great. You won't be disappointed. I bought this bag for military use, because the Army issued bag is twice the size and weight as this one.

Comments about REI Magma Sleeping Bag:

Just received this bag a few weeks ago and went out last week with it. I am amazed at the warmth to weight ratio. I slept in a snow cave(Montana Rockies) with a bivy sack and thermarest and stayed nice toasty. Temps down to 10. I really like the outer shell, the hood and zippers are very functional.
