Recent 3-Season Down Sleeping Bag Reviews

Sierra Designs Men's Backcountry Bed 800 3-Season

rated 5 of 5 stars Sierra Designs thought outside the traditional box in designing the Backcountry Bed sleeping system. Starting with a basic mummy bag, they removed the zipper and provided a curved opening in the top of the bed. They then attached an integrated oversized comforter that allows the sleeper easy access in and out of the bed. What you end up with is a hybrid mummy bag/quilt, providing the best of both worlds. The comforter, with insulated arm and hand pockets, can be left open or tucked into the bag. Full review

Marmot Men's Helium

rated 0.5 of 5 stars Just returned a Marmot Helium bag after two uncomfortable nights in the Wind River Range for cold spots in the hip and upper chest area. Based on my own personal experience I cannot recommend it. I purchased this bag as a replacement for my old reliable Marmot Lithium because, over the years, the down in the bag had seeped through the lining leaving cold spots.   The Helium had great features with the full zip from top or bottom to allow easy ingress and egress and foot ventilation plus the partial… Full review

Kelty Men's Cosmic 20

rated 4 of 5 stars Super affordable sleeping bag. It is perfect for a camper/backpacker on a budget. This bag is not only affordable, it's lightweight and compactable. This is the perfect bag for someone who wants decent performance without shelling out the $550 for the Western Mountaineering ultra lightweight bag (which is totally worth it if you don't have a budget).

Mountain Hardwear Ratio 15

rated 5 of 5 stars Good all around sleeping bag for three seasons. Used it mainly in Northeastern British Columbia. I got the Ratio 15 and my wife got the Heratio 15. Fits me really well and isn't constrictive. The bag feels cozy and warm and seems to regulate heat pretty well. I haven't noticed any cold spots at all. The shell and dry down really help keep the bag dry. The down is placed well throughout the bag and the baffle along the zipper keeps the cold out. The colour is nice and the materials have a quality… Full review

NEMO Nocturne 15

rated 5 of 5 stars Like to snuggle? This bag's for you! Starting my AT thru hike in March made the need to stay warm and cozy critical to my ability to stay the course and NEMO delivered: the unique figure-eight shape, blankey-like material around the neck, and generous hooding made even the coldest nights conquerable. Debating, though, if such a warm bag is the best choice for these summer months... There were some incredibly cold nights on the AT in the first weeks on the trail and NEMO's Nocturne 15 kept me thriving… Full review

Western Mountaineering AlpinLite

rated 5 of 5 stars Great lightweight three-season bag. I bought this bag after taking a nice 30-degree bag on the John Muir Trail in mid-September. We hit some cold weather with nights dipping into the teens. To stay warm, I had to put on every piece of clothing I had and wear it in the sleeping bag. For about 4 oz of additional weight, the Western Mountaineering AlpinLite solved my problem. It is light, super high quality, and fits me great. I got the long version because I am 6'2". One problem I always have with… Full review

Mountain Hardwear Phantasia 15

rated 5 of 5 stars I bought this bag after realizing I was a cold sleeper even in the summer. I wanted something to keep me warm all year out in the wilderness. I definitely found it with this bag! Lightweight, soft, 850 down fill, easy zippers, and great hood. Bag comes with storage sack seen here. Stuff sack comes with the bag as seen here. Puffs up quickly even after being compressed for a while. Very lofty bag, so puffy and soft!   Kept me warm up in Summerland. I love this bag! Super soft and warm and zippers… Full review

Marmot Scandium

rated 4 of 5 stars A great choice for cold sleepers that comes with lots of bells and whistles. The hybrid fill design gives you better comfort and weather resistance, but comes at the price of being slightly bulkier and heavier. Still a good backpacking choice. I'm a cold sleeper, and the features on this bag keep me warm down to 30-degree nights with a merino baselayer and socks. I love the cinchable hood and the extra flap at the next and shoulders. These features work together to keep out the cold. Both have drawstrings… Full review

Western Mountaineering Apache MF

rated 4.5 of 5 stars A fabulous bag for summer mountain backpacking. Great 3-season bag. Summary - You can't go wrong with this bag for summer mountain backpacking. Warm with low weight. Anti-snag feature on zipper makes that midnight bathroom run a bit easier. And the way I like to re-hydrate with lots of warm tea after dinner, I cannot say enough about the zipper design. Also the shoulder collar (see pic) which is separate from the hood, does a great job in keeping any cold draft out, and on warmer nights, it can… Full review
