Recent 3-Season Down Sleeping Bag Reviews

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

Sierra Designs Men's Backcountry Bed 800 3-Season

rated 4 of 5 stars 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°

rated 4 of 5 stars 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

NEMO Siren 30

rated 2 of 5 stars Not the quality and performance you pay for. This is a DUCK down semi-sleeping bag/quilt. Not the same quality that my original Siren 30 was. In 2013 the same bag/quilt used 850 GOOSE down and seems still like a far warmer and better quality for the cost product.   Rating estimate of this bag is more like 45°F. Beware of not getting quality for the cost. Full review

Western Mountaineering Antelope GWS

rated 4.5 of 5 stars This sleeping bag feels as if you are inside of a cloud. The bag's rating makes it a superior choice for winter camping. I love the way the mummy bag is designed. You have drawstrings by the neck and also by the hood. This lets you control warmth and air flow. The two zippers make it ideal for venting heat from the foot area if too warm and also unzipping the top zipper to cool off your torso. The bag keeps me super warm in cold weather. I found out that I can also use it as a quilt if I unzip it,… Full review

Marmot Never Winter

rated 4.5 of 5 stars Looks high quality, warm, and skin friendly. Just received the bag, looks high quality. The zipper did get stuck a bit as I played around with it, but that may be due to the bag being brand new. 11/28/16 Update: Very warm, definitely wouldn't call it a summer bag. The -1c rating is in fact the average rating for men and women. It says 2c for women and -3c for men. It has great compression and for less than 900 gram that is great value. Full review
