Recent 3-Season Down Sleeping Bag Reviews

Kelty Men's SB 20

rated 5 of 5 stars Testing the SB20 down to 13 degrees. After an exhaustive search for a shoulder season bag, I stumbled across the SB20 on sale and couldn't pass it up. I had looked at the Montbell bags, which were heavier and not as warm. The Western Mountaineering Alpinlite was 2 oz lighter, but was more than double the price at $540. Not a good price per ounce saved in my opinion. I knew that Kelty made bombproof backpacks, but I've never considered one of their bags, because they've always been too heavy. Full review

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

rated 4 of 5 stars Very happy with the flexibility we have with these sleeping bags. Good product! There are very few conventional rectangular sleeping bags out there that are insulated with down. You'll find a few if you look where hunters shop; and you'll find a few in the Western Mountaineering catalog. Other than those I think these L.L. Bean sleeping bags are the main option for rectangular bag dimensions, and flexibility, without the bulk and weight of synthetic insulation. My wife and I have had a pair of these… Full review

Marmot Men's Helium

rated 5 of 5 stars Lightweight, super warm, 3-season sleeping bag. 15 degrees, super comfortable and warm 850 fill down. Best used for camping/backpacking in the fall/winter time. Definitely would recommend if you enjoy being warm and comfortable. This bag is really amazing, I've used it in the low 20s and it worked perfectly. I think the comfort rating is around 20 degrees and the lower rating is 16. I spent 10 days on my sleeping pad only in the backcountry of Moab, Utah. I was wearing layers and warm hat, and a… Full review

Western Mountaineering MegaLite

rated 5 of 5 stars Warm and comfy to 30°, survival rating to much lower. I thru hiked the AT with this bag, starting in April and ending in October. I saw snow, ice, hail, frost, to temperatures of 110°. When it was cold I only recall being chilly once, and it was getting caught at high altitude in the Smokies in a storm. When it was hot the bag was used as a pillow or pad top, but even in the hot humid Appalachian summers it gets chilly sometimes in those hollows and sometimes I would zip it up in summer. The only… Full review

Marmot Never Summer

rated 3 of 5 stars Good budget down bag. 650 fill down is just as warm as the lighter stuff but heavier. Fits true to size, normal is for 6'0'' and shorter. Has cold spots in the foot box. I've had this bag for years. It is my first winter bag. The particular one I own is the orange and rust one with the black inside, not the newer all orange or all red bag. My biggest gripe is not that this is not ultralight, it is what it is and you get what you pay for.  My biggest con for this bag is that the foot box is so narrow… Full review

REI Sub Kilo +15

rated 5 of 5 stars This bag was one of my favorite pieces of gear for my 21 days on the the Appalachian Trail. I would recommend it for anyone looking for a good spring or fall bag. I'm 5'9" and 180 lbs and slept comfortably even while ice formed on my rain fly. I started hiking the Appalachian Trail from Springer Mountain this spring. Started March 27 and traveled 160 miles in 21 days. This bag did great. There were nights I woke with ice on my tent and I still slept comfortably. I haven't used it down to 15 degrees… Full review

The North Face Blue Kazoo

rated 4.5 of 5 stars This is a fantastic, lightweight bag for backpacking and general camping. I've had my Blue Kazoo for over 20 years, and it has never let me down. This is a fantastic, lightweight bag for backpacking and general camping.  I've had my Blue Kazoo for over 20 years, and it has never let me down.   I now let my 7-yr-old son use this when we camp, and it kept him cozy and asleep in 40 degree temps even after rolling off of his Therm-a-Rest pad. As I have gotten older (bigger around the waist), the bag… Full review

Kelty Ignite DriDown 28

rated 4.5 of 5 stars This sleeping bag is designed for warmth even in damp conditions. The DriDown technology keeps the cold out and dries fast. I bought this bag to replace my 20-year-old down bag after waking up freezing on a wet 50 degree night. This bag is great for warmth in damp conditions and packs down light. I bought it to take fall camping and fight off foggy mornings. It's rated to 28 degrees but I found that it's closer to 40 degrees for comfort. I am 5'8" and made the mistake of buying the regular length… Full review

Kelty Men's SB 20

rated 4 of 5 stars Lightweight 800-fill Dri-Down bag kept me warm and dry. I took this EN20 rated bag on a backpacking trip into the Sangre de Cristo mountains of New Mexico just as the region's "monsoon" season started. Camping above 9,000 feet with rain and overnight temps dropping into the upper 30s and lower 40s had me worried, but the SB 20 handled the soggy conditions without a problem. The waterproof coating at the head and foot kept the bag dry even with heavy condensation inside the tent.  I think the EN… Full review
