Recent 3-Season Down Sleeping Bag Reviews

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

Kelty Cosmic Down 21

rated 4.5 of 5 stars This bag packs small and keeps you warm. While it isn't the warmest bag on the market, it is a great option for the backpacker on a budget. In the balance of price and quality, the scales are tipped to quality. I bought the Kelty Cosmic Down 21 on sale a couple of months ago. It was on sale because Kelty just rolled out the new Kelty Cosmic Down, so I decided to go for it. So far, I've been pretty happy with it, and the pros definitely outweigh the cons to me. I've used the bag in the Smokies on… Full review

REI Igneo Sleeping Bag

rated 5 of 5 stars Great bag, I would buy another one. You can't go wrong buying this bag. It has the quality or exceeds the quality of much more expensive 20 degree bags. I used this bag on an AT thru-hike 2015. What I like most about the bag is it's ultra-lite, very packable, very water resistant and a perfect fit for me at 165 pounds 5'10", using the regular bag. I found it to be a very comfortable bag. I washed the bag using cold water and dried the bag in a dryer on low heat using drier balls to keep the… Full review

REI Magma Sleeping Bag

rated 4.5 of 5 stars Great product. Kept me warm down to single digits. I have used this bag for the past two winters and have been really happy. It's kept me warm down to single digits. I think the DridDown helps because I never have any clumping, but often have frozen condensation on the outside of the bag. Zipper snags and even caused a small tear in the bag. Full review

Kelty Men's SB 20

rated 5 of 5 stars An excellent 3-season down bag for the money. Quality made product and impressive customer service. I've turned several people on to this bag. Was able to purchase for a promotional price, but wouldn't hesitate paying retail. Me: 6'1" and 210 pounds. I chose the long bag and it fits perfectly. My tent: Big Agnes Slater UL 2+. The Slater series has no mesh so it does help my stabilize temps in colder weather. Ground Pad: Big Agnes 15 degree insulated Q-Core pad. (5 stars plus for comfort! best night's… Full review

Marmot Sawtooth

rated 4 of 5 stars Long lasting, warm bag that serves its purpose well. Great hood system and nice feature set. The zipper is poor on my model but newer purchasers suggest this has been fixed. I recommend it as a great value. I have owned my Sawtooth for more than a decade and in that time it has seen more than a 365 days worth of use, including at least 180 days worth of subfreezing temperatures. So this bag gets a big plus for longevity. The lowest I have had the bag is 12 degrees and the highest is 40 (because… Full review

Kelty Men's Cosmic Down 20°

rated 5 of 5 stars A down bag for $115—it doesn't get better. Got the long from Sierra Trading with deal flyer discount over $100 off retail price. Very nice looking bag, the two blues look great. Added a 13L Granite Gear eVent waterproof compression stuff sack, and when compressed the bag compresses to about the size of a large shoe box (7"x8"x12"). Have always bought/used synthetic bags (have 55, 35, 20 degree synthetic bags), because all but the 20 compress small enough that they don't take up a lot of space… Full review

Sierra Designs Zissou Plus 700 3-Season

rated 4.5 of 5 stars New zip down 1/2 quilt is the best idea ever! I've been needing/wanting a new bag for colder weather that is also compressible. I've never been willing to dish out hundreds of dollars for a top of the line bag because I mostly backpack in the summer months. But after a freaky cold night on Labor Day weekend at the forks of the kern (27 degrees at night, when it was 90 in the daytime) I decided I needed to look into upping my warmth, but didn't want to sacrifice weight. Plus my girlfriend and I just… Full review
