Recent 3-Season Down Sleeping Bag Reviews

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. I love this bag! Super soft and warm and zippers actually are a breeze to get in and out of bag in the middle of the night. Great hood, actually fits my head like it should. Nice stowaway pocket for phone or MP3 or tissues. Packs down small. I won't need any… 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. 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. My Use - I have used it the Sierras and Rockies where temps dipped to 20 in the fall, and had no problem. On windy and wet nights at 20 degrees, the breeze coming… Full review

Marmot Sawtooth

rated 3.5 of 5 stars Just what the doctor ordered. Packs down nicely without a stuff sack and nicely warm. Roomy enough to sleep comfortably while keeping you very warm. Some say it's on the heavier side, but I think it's perfect. Great features and the treated down is a nice safety net should the bag become damp/wet. Full review

NEMO Rhumba 15

rated 5 of 5 stars Side sleepers, this is your bag! Crawling into this bag for the first time, I knew I had made the right decision. I wanted a bag that allowed me to comfortable sleep on my side, move around and not feel confined. This bag does exactly that. NEMO's intelligent design gives you all the comforts but does not sacrifice in quality. I tested this bag out recently on a 30-degree night outside of Bryce Canyon and was cozy the whole night. The extra little "flap" that NEMO had added to their bags makes you… Full review

NEMO Nocturne 15

rated 4 of 5 stars Very roomy sleeping bag, excellent to sleep on your side with one knee pulled up. The flap is great for heat regulation and for snuggling. The pillow pocket is a nice finishing touch. Haven't tested it in cold temperatures yet. I still have to test this bag in cold temperatures, but as the summer is coming up, this might take a while. So far this bag seems great. It's very roomy. This was a really important factor for me as I have spend sleepless nights in my tent because I couldn't move around… Full review

NEMO Sonic 0

rated 4 of 5 stars Used this bag for a February through April section hike of the Applachain Trail this year. It is an outstanding cold weather bag, and as the nights warmed I opened the" gills" to make the bag cooler. Used a large Sea to Summit compression dry sack to carry it. My husband and I planned on hiking the AT this year with a February start. Knowing we would encounter below freezing temperatures for more than a month I searched for a good cold weather bag for the weight ratio. We settled on the Sonic Nemo,… Full review

Rab Men's Ascent 700

rated 4 of 5 stars Warm, lightweight, highly packable, roomy, designed to pair with a similar bag, wide temperature range. This sleeping bag is a desired addition to a backpacker's load list for at least 1.5 out of 3 seasons. No need to compromise temperature and sleeping comfort for weight any more. When choosing a sleeping bag for backpacking it's a hard battle between warmth, weight, and price. Ideally a sleeping bag is very warm, exceptionally lightweight and packable, and costs almost nothing. But this will never… Full review

Campmor 20 Degree Down

rated 4 of 5 stars I have owned two of these bags. The first one I used on an AT thru hike on nights as cool as the teens. The following year I used it 10 nights on the Colorado Trail again in the teens. By the second trip it was getting drafty, but I had about 150 nights in it and I was quite dirty. I think I washed it poorly and never got the loft to restore. I bought a second one and have about 20 nights on it with no issues. I will keep buying these if they make them. My first experience was on an AT thru hike. Full review
