NEMO Disco 30

It’s comfortable, stayed warm when camping in the 20s. Packs up nice and small. Perfect for backpacking. Have taken this bag on extended backpacking trips and it met all my needs. Kept me warm even when it was in the 20s. It was lightweight in my backpack and always fluffed up nicely when I took it out of the stuff bag. Love the shape as it gave me extra wiggle room. The foot box gave me extra warmth right where I needed it. Full review

Feathered Friends Swift

I purchased this Swift at the FF store across from REI about 1998. The Swift is light, compresses well, and holds up to a great deal of abuse. It has kept me comfortably warm down to its published temp range of 20° F with only a base layer inside a homemade liner. I definitely recommend it for PCT section hikers from Oregon North to Manning Park; as well as weekend or holiday treks where you may encounter wet/cold conditions. DESCRIPTION AND PURPOSE This is a Swift, serial number 95448, 800 fill… Full review

Sierra Designs Men's Backcountry Bed 700 / 20 Degree

Good 35+ degree bag without zippers. Do not recommend below 30 degrees without additional support. Great for side sleepers and folks that get out of the bag at night and hate struggling with zippers half-asleep. As a side sleeper using a CPAP, I've always struggled with sleeping bags. My "go-to" bag for 20-40 degree weather is either a Kelty Cosmic 20 or Cosmic 0 bag. They work, but the 20 is more like a 30-degree bag and the 0 is more like a 20-degree bag. When Sierra Designs released the zipperless… Full review

Sierra Designs Cloud 800 / 20 Degree

A bag with the magic of 800 fill DriDown for about $100 less than the other bags in the same weight category. Sierra Designs Cloud 20 800 fill down Regular: 1 lb 13 oz In the mountains you need your gear to be as light as possible and still able to do its job. Being light reduces fatigue and lets you move through hazard zones faster thereby reducing your exposure to risk. In short, light is right. Another philosophy is summarized by, “pack light, freeze at night,” the idea that comfort and good… Full review

The North Face Hightail 3S 15

Perfect. A great find after lots of research. I did a lot of research on bags of this temperature rating that were under one kilo. This bag replaced a much heavier sleeping bag and it seems every bit as warm. I have not had it down to the rated 15 deg. F, but I believe with long johns and good insulation under it, it would be satisfactory for me at 15 deg. F.  (I am a warm sleeper, by the way). I have had lots of well made mummy bags and I find this one is a perfect fit for me. Others have been… Full review

The North Face Men's Blue Kazoo

High expectations, poor performance. Bought this North Face bag at a local REI. I used it for several years in a variety of settings, from indoor use to summer hiking, fall, even some winter hikes. My biggest complaint is its temp rating. My bag says it is a 15-degree rating. YES, I always stored it loose, never compressed. The bag was well taken care of. After several nights over several different outings I was sure to bring extra clothes to sleep in if I knew temps would drop below freezing. This… Full review

Hyke & Byke Eolus 800 Fill Power 15°F

The best bang for the bucks. I bought the regular size black/orange Eolus 15 and I'm impressed with the bag. It was shipped fast and delivered boxed in the compression stuff sack, so it needed to be fluffed. I put it in the dryer on low for 20 minutes with my dedicated tennis balls and, voila! The fabric has a very light and silky hand. Using the zipper pull makes for snagless opening and closing of the YKK self-repairing two way zipper. Seams are clean and flawless. I like the ability to shift… Full review

Sierra Designs Nitro 800 / 0 Degree

The Sierra Designs Nitro 800, 0-degree women’s sleeping bag is a lightweight, warm bag that compresses to a small size and is comfortable to sleep in. I’ve been testing the Sierra Designs Nitro 800 sleeping bag all summer and can report that it’s a very warm bag that is lightweight and comfortable. I love my other bag, the Sierra Designs Backcountry Bed, but when the temps dip down into the teens and 20s, I prefer the added warmth of a mummy style bag. I was excited to see this new offering… Full review

Sierra Designs Men's Mobile Mummy 600 3-Season

Who came first, the chicken or the egg? Was it Sierra Designs or Exped? I dunno, but I like it. It's hard to say though whether it's an overstuffed extra long down vest or a warm roomy cocoon for human transformation, but it cries for transportation anywhere in camp. For me this design works the best, as I'm up and down numerous times during the night. With a side zip it works fine until it's colder. Then this bag shines, because I can just leave it on and unzip to satisfy the nature call. I think… Full review
