rated 4.5 of 5 stars
REI Igneo 25

I’ve gotten through some very cold nights at higher altitudes by wearing cold weather gear and a bag liner inside my Igneo 25 long. Good value and quality with some very nice design features for the price. The light weight and compressibility is outstanding. After two years it is still my “go to” when heading out with a backpack. Thumbs up! Full review

Wiggy's Ultra Light

Heavier than advertised, terrible customer service. This is one of two Wiggys sleeping bags I recently purchased, the other being a Superlight of the same design. When both came in I immediately inspected and weighed them only to find that each weighed in right at a pound  heavier than advertised; 4.25lbs for the Ultralight, and 5.06lbs for the Superlight. Since these were meant to be lightweight, warmer weather substitutes for the Ultima Thule bag  I have owned and loved for years I was pretty… Full review

Western Mountaineering SummerLite

Used this for a month in the woods for military training exercises. It's great for sleeping outdoors even if you don't have a cushion or sleeping pad. I got one for a military training exercise since the army ones aren't as comfortable. I didn't mind the price for comfort, however, it doesn't do well in wet conditions. Moisture still seeks in and gets a weird smell. If you're not going to be in a wet area, it's perfect. The Summerlite rips TOO easily, I found a gap on the back after sleeping on… Full review

Big Agnes Lost Ranger 15°

Great bag and a great price, but not a 15 degree bag for us! (Roxy Ann included) Temperature ratings are very personal and depend a lot on how much a heat a person produces and puts off generally; also what state of rest a person is in when they use the sleeping bag, and how much they've had to eat can play a role in sleeping comfort when you are required to make your own heat. I have used this bag and its accomplice the Roxy Ann (my gf has) for over two years and probably 50+ nights (100 nights… Full review

Big Agnes Torchlight UL 20

The Torchlight UL 20 is a fantastically cozy and versatile backpacking mummy bag. Super spacious when you want, but snug when you want that, with customizable zipper options. The ultralight 850 fill power Down-Tek makes it a great choice for ounce-counting backpackers. I have been using a Mont-Bell UL SS Down Hugger #4 sleeping bag for about ten years. It has served me well, being very lightweight (1.5 lbs), and warm enough most of the time (rated 34°). It also has stretchy elastic baffle stitching,… Full review

Wiggy's Super Light

Bag failed to keep my feet warm at 30 degrees and you saw on different sites where people were having the same issue with the newer bags now. The older ones don't have that trouble. There is just not enough installation in the foot area in the new ones. Texted Jerry Wigutow about it and he had a very negative response about, told me first off get in a tent on a pad, then he told me to get a pair of booties. Then I sent him copies of other sites having the same trouble because he said he never had… Full review

Outdoor Vitals StormLoft 30-Degree Down TopQuilt

The 30 Degree Down TopQuilt is one of the most affordable, lightweight and reliable sleeping bag options on the market. Weighing just 18 ounces, it's built like a workhorse but performs in an elegant way. If you’re looking for an affordable-yet-reliable quilt for backpacking, look no further. Outdoor Vitals’ 30 Degree Down TopQuilt is unmatched in its efficiency. The 800fp quilt is compressible beyond relief, warm when it counts and it still costs a fraction of competitive products.  The 30… Full review

Big Agnes Diamond Park 15

Big Agnes calls the Diamond Park 15 a sleeping bag, but it really isn't, except for sometimes when it is. It is more of a flexible sleep component system that converts from a back country bed style unit into a full featured, standalone quilt or even a mummy style bag with the optional Park Bag Wedgie Expander. Great for those who want flexibility without having to purchase a quiver of bags and quilts. The Big Agnes Diamond Park 15 uses 600 fill DownTek for insulation and converts from bed, to quilt,… Full review

Western Mountaineering SummerLite

I have tested WM Summerlite in the Colorado Rockies (say, above 9000 feet), where you can expect frosty nights at any time. I would not recommend to venture out, even in midsummer, with less than a 20°F bag. BUT 32°F Summerlite did quite well in keeping me comfortable in July. I was dressed very warmly, ofc. (comfortable is the right word here, not warm). I guess this is because of the comtinious baffles; there's an unbroken four-inch layer of down separating the two nylon shell fabrics. This… Full review
