Mountain Hardwear Spectre SL 20°

Great bag for sleeping in cold and damp environments. I'm retired Army Infantry and am an avid outdoorsman. I live in North Carolina and as such am exposed to all types of weather, often within the same week. This is by and far the best bag I have ever used for temps down to the 20s (F) and lots of humidity when it's above 32 degrees (F). Especially considering it weighs in under 3 lbs. Wish I had this bag when I was active duty!! I have slept in this bag outside at 22 degrees (F), using it as a… Full review

Marmot Never Winter

Warmer than its rating, lighter than many and bullet proof. This bag is definitely warmer than its rating. In a hammock at negative 8 degrees Celcius (I'm from the UK) I was plenty warm enough in long johns and a fleece jacket. No draughts or cold spots I could find and nothing scratchy in your face when bundled up. I'm short and wide, so I don't reach the footbox completely, but I like the extra space at the shoulders. I like to turn IN the bag, not have the bag turn with me. The zip is full length… Full review

Big Agnes Lost Ranger 15°

This is indeed a 15° sleeping bag when used with an appropriate R-Value pad.   I have read a lot of very favorable and very negative reviews on the Big Agnes Lost Ranger with very little in-between. I found it odd that a piece of equipment would be judged at such extremes, so I decided to pick one up and see what all the hype was about. To try and remove the heavy bias that this item seems to draw, I set up this little experiment to see just how this bag worked. Because sleeping comfort is such… Full review

Western Mountaineering Apache MF

This bag is amazing! I just spent New Years, Jan 1, 2015, in the Utah desert. It got down to 12°F in my Springbar. This bag didn't just keep me not cold, but with the draft collar and the hood all the way cinched I stayed toasty warm. This bag will definitely put any other three-season bag to shame. I spent four nights in this bag in the Utah desert on New Year's Eve in freezing cold temperatures and stayed completely and totally warm at night in the sleeping bag. The draft collar works amazing… Full review

Eddie Bauer Karakoram 0 StormDown

Great deal on a 55% off sale, but two problems made me send it back. I just got this bag and will be returning it to EB.  As listed above it needs either more fill or smaller tubes to prevent the down from shifting during use and thus creating convective heat loss. Additionally the loose fill means more space to heat. The main gripe is a very poorly designed and located neck collar.  To wit: located at my mid sternum (I'm 5' 10"), not at my neck and shoulder area.  no Velcro closure at the zipper… Full review

The North Face Men's Blue Kazoo

Quality construction, great value. I purchased my Blue Kazoo in 1986 (yes, almost 29 years ago) and have used it, on average, 10 nights a year for backpacking. It has failed to keep me warm only once while winter camping in the Rockies when temps dipped outside my tent to about -10°F. Granted, on nights when temps dip below about 25°F, I start putting on long undergarments to sleep, but doing so has kept me toasty in this bag down to about 0°F. Most recently I slept outside at about 11,000 feet… Full review

Kelty Men's SB 20

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°

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

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
