Recent 3-Season Down Sleeping Bag Reviews

Sea to Summit Trek TK II

rated 5 of 5 stars Excellent down bag for a variety of conditions. It's lightweight, packs down small, does better in wet weather than other down bags, and is very comfortable. This is the fourth backpacking sleeping bag I've purchased, and the second down bag. I purchased it when backpacking in Chile in 2012, realizing that the very lightweight synthetic bag that I had with me at the time would not keep me warm further south in Patagonia. I used it camping in all conditions in southern Chilean Patagonia, as well… Full review

NEMO Strato Loft 25

rated 5 of 5 stars Like sleeping with a comforter at home. This bag is designed to work WITH your current sleeping pad or mattress. I use a Therm-a-Rest NeoAir 25" wide mattress. It fits the bag perfectly. Zips up on both sides making it very versatile. It should be called more of a sleep system than a sleeping bag. Warmth: The bag keeps you warm. I like to wear basketball shorts and t shirt to bed. Kept me warm in upper 30 degree (F) temps. Fit & Comfort: The overall fit and comfort is amazing! The length for… Full review

Marmot Couloir

rated 5 of 5 stars Excellent bag if you want comfort and durability. I have had this bag for years. It is incredibly comfortable. Marmot stands behind its gear. I had a house fire and part of the bag was burnt/singed/melted. They were able to repair it like new for me. I have a left hand zip and my husband has a right hand zip. His is several years newer than mine but they mate perfectly. The bag packs and compresses well and washes up nicely after a long trip. Full review

REI Igneo Sleeping Bag

rated 4.5 of 5 stars So far so good. This bag has held up and kept me warm for a year, even when camping in shoulder seasons in Alaska and the Sierra. I carry it on all kinds of backpacking trips and I have no issues with it. I like the packed size and weight. It fits me well (5'7" broadish shoulders). It's warm but not sweaty. Zipper has been reliable. I was shopping Western Mountaineering and Feathered Friends, ready to drop the big money, when a friend who worked at REI showed me this one and told me when it was… Full review

Marmot Men's Helium

rated 5 of 5 stars Awesome bag! Lightweight, warm, durable, compressible. Just a great piece of equipment. Warm, durable, compressible, lightweight and covers three seasons well. Inspires confidence: I know I can survive virtually any weather condition with this bag. Can get warm in summer, so sometimes has to be unzipped! Full review

Mountain Hardwear Ratio 15

rated 5 of 5 stars I would recommend this bag for anyone looking for a down bag on a budget. Perfect for three-season camping! I was replacing a Big Agnes mummy bag rated at 20 degrees. I wanted something different and without an inconvenient sleeve system, but I didn't want to spend an arm and a leg. Come forth the Ratio 15.  Purchased at Next Adventure where they accept old goods and in return give store credit which I'd accumulated the amount needed. This bag was brand new and on sale for a steal at $169. I couldn't… Full review

L.L.Bean Down Sleeping Bag with DownTek, Rectangular 20°

rated 2.5 of 5 stars Don't count on staying warm at 20°F in this bag, based on my experience with the older versions. I've had three of the older versions of this bag. I use them indoors, on my bed. They are very comfortable, silky feeling inside, and also roomy. But, as noted, the temperature ratings are not something to be believed. In my case, below 55°F I have to start bundling up and adding extra covers. I have a very good down quilt to cover the bag, also an inner fleece bag when necessary. And multiple layers… Full review

The North Face Inferno 0F/-18C

rated 3.5 of 5 stars Comfy, super warm sleeping bag. No issues in the cold! I brought this sleeping bag on my trip from Patagonia to Alaska, and was really happy to have such a warm and comfortable "bed". The bag keeps you really warm due to a closed leg box. The central zipper only opens until waistline. I never had to wear clothes inside. Even at minus 8°C (coldest night) I was sleeping in simple underwear, no t-shirt necessary. (Disadvantage: this sleeping bag is so warm it can hardly be used inside a house, which… Full review

Marmot Men's Helium

rated 5 of 5 stars Great 3+ season bag for those with shoulders too large for an average mummy. I would say this is probably one of the best mass market, 3-season down bags available for the price. Lots of loft, packs down reasonably small considering it is actually rated to around 10 degrees for men (despite the name Helium 15), and the long version is very generously cut for guys with larger shoulders or those who wish to extend the temp range with additional layers. I have yet to use near the limit, but so far… Full review
