Kelty Tuck 20

Kelly Tuck 20 long—brilliant for tall side sleepers. I’m six foot four and find it really hard to get comfortable on most camp sleep systems. The Kelty Tuck 20 long enables me to move around being a side sleeper and I thoroughly recommend it. Pack size is an issue; use an Exped  compression bag, which gets it down in size well. It’s a trade-off for being tall and not paying over £100 for a sleeping bag. I’ve used it in freezing and 5c temps and it’s really warm. Full review

Marmot Helium 15

Wide temperature range. Light. Warm. Roomy. I own several Marmot sleeping bags from the lightweight Hydrogen to the extreme conditions Cwm. The Helium is my all around favorite, the one bag I would own if I could only own one and the one I reach for most often. In my experience, high quality down has a much larger temperature range than synthetics. The Helium has a design feature that maximizes this versatility that you will either love or hate. Most sleeping bags have a side baffle to prevent the… Full review

Marmot Trestles Elite 20

With a good price and low weight, it is an excellent option for backpacking and traveling in three seasons. This is the sleeping bag I use for my three-season outings, where temperatures can reach 0° C (32° F). 1) Warmth: The most extreme temperature in which I have used it was -6° C (21.2° F) and being with a warm layer I had no problems. But I would recommend it for situations over to 0° C (32° F). 2) Fit & Comfort:  It is a comfortable sleeping bag, not too tight at the height of… Full review

Mountain Equipment Glacier 700

Great overall materials for the price, but a few major flaws. I would love to love this bag. I searched for a long time and for its price class (<300 euro), it has one of the best specs/weight ratio. It is warm (rated for 5°F, -15°C ), very lofty (700 cu in down,  >=90% down), has a water-repellent outer material, the down distributes well and stays in place in the baffles. However there are a few problems for this bag that made me return it after testing at around -1°C (~30°F). I am… Full review

Sierra Designs Nitro Quilt 800 / 20 Degree

I bought one based on reviews. I had some issues but the company stepped up and fixed the issue. I am very happy with the new one. I bought one based on the reviews. I really like the design.  I had a minor issue on delivery. I contacted the company and their response was slow but they took care of me. They gave me a return number and offered to replace it. The new one is perfect. Full review

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
