Recent 3-Season Down Sleeping Bag Reviews

Big Agnes Lost Ranger 15°

rated 5 of 5 stars This sleeping bag is light and versatile. It is useful in warm to cold weather. This bag has performed well over the last year. I am a Scout leader and use it every month. During the hot summer months I sleep mostly on top of it. Recently I took it on a week long trek in the mountains. With the DownTek down in it, it stayed warm when ground moisture got one side of it wet. The bag dried quickly draped on top of the tent. It is very compressible making more space for things like food in the pack. Full review

Sierra Designs Men's Backcountry Bed 800 3-Season

rated 5 of 5 stars I'm a bigger guy, and never slept well in a sleeping bag...until I got the Backcountry Bed. I have two sons in the Boy Scouts and have spent my share of evenings in a tent/hammock. I'm a bigger guy, approx 5'10" and 240 lbs. I find most mummy bags constricting and have struggled to get a good night's sleep. That is, until I recently tried the Backcountry Bed by Sierra Designs. We were heading out on a 4-day, 42-mile hike and I was determined to find a quality bag that's comfortable...and boom, I… Full review

Patagonia Hybrid Sleeping Bag

rated 4 of 5 stars The Patagonia Hybrid Sleeping Bag is an “elephant foot” style bag designed to minimize the weight a climber carries by insulating only the bottom half of the bag and relying on insulation already required (a jacket) to keep the torso warm. The combination of high lofting 850 fill traceable down, impressively constructed baffles/footbox and 1.2-oz 15-denier 100% nylon ripstop upper (the same fabric as their famous Houdini wind shell) makes for an incredibly packable and warm night's sleep. This… Full review

Kelty Cosmic 4

rated 4.5 of 5 stars The Kelty Cosmic 4 is a great sleeping bag that's snug even on cold winter nights. It's puffy. It's comfortable at 19 degrees Fahrenheit and up. I'd recommend it if you want a warm cozy night. The Kelty Cosmic 4 is a very warm 4-degree bag that's comfortable at 19 degrees. It is 6 feet long, has lots of hood room, and plenty of foot room for me. So overall it is very comfortable. The bag is easy to get in and out of since it has a wide hood (as long as it is tightened). The bag doesn't let in moisture… Full review

Marmot Angel Fire

rated 5 of 5 stars I've owned the Marmot Angel Fire bag since 2004/5(?) and it has been my primary bag. Excellent compression, durable exterior, no defects/issues for over 12 years with an average of 8+ trips a year. Pros: lightweight, small pack size. Cons: mummy style can be difficult to sleep comfortably in as a side sleeper, but this is user preference. The only reason I didn't repurchase this bag is that my personal dimensions have changed over the last couple of years and the mummy bag style just isn't as fitting… Full review

Sierra Designs Frontcountry Bed 600 SYN 2-Season

rated 5 of 5 stars My go-to for any trip where weight isn't the largest concern. I've been a mummy bag user for decades but it was time for a change. I use this mostly on weekend trips, car camping, and disaster response. I've spent about 100 nights in this bag and there is virtually no wear at all. Most of these nights are on a Red Cross cot while deployed with Team Rubicon. Sleeping temp and comfort is extremely subjective, but I have found this comfortable without a base layer to about 40-45°. For reference I… Full review

Marmot Gopher

rated 5 of 5 stars This bag will probably be too hot for mostly just weekend campers unless you are in colder temperatures. I worked in an outdoor store in N.J. (mid '90s) and this bag and several other Marmot bags were the top of the line and because of the price tag ($500+) they sat hanging up on the rack for a while. Finally because of a discount, and they wanted to put new models up, I bought the bag. I believe I paid $300 for it. It unpacks and really puffs up upon laying open.  I used it to go winter camping… Full review

Marmot Gopher

rated 3.5 of 5 stars The Marmot Gopher works very well, and it lasts a long time. It keeps you comfortable from 30+ degrees Fahrenheit. After awhile it starts to lose feathers, but not fast, just a few could stick out and eventually fall out. It is great for backpacking because it stuffs very small and isn't too heavy. Overall I think the bag is a good choice for a warm cozy night.                                             The Marmot Gopher bag is very warm and comfortable at 30 degrees plus. Full review

Big Agnes Lost Ranger 15°

rated 4 of 5 stars This review is for the older semi-rectangular model. Really comfortable. The comfort level is around 35°-40° F. This bag uses the integrated Big Agnes pad system. The bag relies on the pad for the insulation on the bottom. This reduces weight and eliminates down where it would otherwise be compressed and lose its insulating value.  Warmth: Having slept in this bag in temps down to 15°F and up to 40°F now, I can say that the bag's comfort rating with a base layer (fleece 1/4 zip and light pants)… Full review
