Recent 3-Season Down Sleeping Bag Reviews

Patagonia Hybrid Sleeping Bag

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

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

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

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

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

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°

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

Sierra Designs Men's Backcountry Bed 800 3-Season

Plays well within its limits. Purchased a Willow Bough (green) Long on Amazon on July 13, 2016. Just finished a 4-day backpacking trip January, 2017 and an overnighter February, 2017 on the Ouachita Trail in Arkansas. On the 4-day trip. We basically spent two of the four days below freezing. On the overnighter the high was 45 degrees Fahrenheit and the low was 34 degrees Fahrenheit. The bag is very well thought out in general. The back of the bag to about the knee area has no insulation whatsoever. Full review

Mountain Hardwear Men's Phantom 0°

Great option, but maybe not the best option. Overall a great bag. I tested at a local camping store but purchased from Sunny Sports as they had the bag for $120 cheaper. I went with this for colder Colorado hikes and it holds up well down to near zero temperatures. I was between this bag and comparable options from Feathered Friends and Western Mountaineering. In the end it came down to this bag and the Western Mountaineering Antelope. This bag was heavier than the Antelope and did not have continuous… Full review
