Therm-a-Rest Parsec 20F

A super warm sleeping bag with some unique features and qualities. I actually won this sleeping bag in a Trailspace competition, so thanks, Trailspace and Therm-a-Rest. I wanted to put this bag to the test before I wrote a review. The good news is that I am super satisfied with this bag. I have four other sleeping bags (some synthetic, some down) to which I can compare this bag. I've used this bag backpacking in Canyonlands NP in sub 20 degree weather. In Guadalupe NP in sub 30 degree weather. In… Full review

Klymit KSB 0 Down

This is a very comfortable, warm bag. It is very stretchy, which makes it ideal for people like me who don't sleep like logs. I would recommend it for any season, given the weather isn't too extreme. I got this bag in December, and so far I have been able to use it several times in high altitude, snowy conditions (in Colorado). I haven't had a chance to use it in summer weather yet. So far, it's kept me nice and warm and given me some nice sleep. The bag is really stretchy, which is great. I don't… Full review

Sierra Designs Cloud 800/20 Degree

Excellent zipperless women's bag. Truly feels like you're sleeping inside of a nice, warm cloud. I finally got to try this bag out this past weekend on the Buffalo River Trail in Arkansas.  The temperatures at night ranged from around 45-55° so I wasn't truly able to test the warmth of the bag. I found no drafts in the bag, except if you don't put your feet in the right way, they slide out of the footbox in the slot. The length was perfect for me (5'6") and it fits like a standard mummy bag. I… Full review

Marmot Teton

Astonishingly good for the weight and pack size. Astonishingly good for the weight and pack size. Kept me warm down to the coldest of British temperatures. Furthermore, weight is very low and sat alongside my other lightweight gear very efficiently. Used in the Lake District for several nights with barely any problems whatsoever. Did get a little wet on day 3 though, some of its efficiency was temporarily lost, but when the sun came out I was able to dry it fairly quickly during a lunch break. Full review

Sierra Designs Cloud 800 / 20 Degree

One of the best option for a warm and light sleeping bag. I was really skeptical with the zipper-less design of the bag but it proved to be a non-issue. It's quite a warm bag but I'm generally a warm sleeper so I may not the be the best gauge for that, but it seems to do the job well in that regard. The fit is excellent with lots of room to move about. I would classify it as a wider than normal mummy bag. I'm 6' tall and the fit is perfect. The added foot vents are a nice touch when you need to… Full review

Katabatic Gear Alsek

The Katabatic Gear Alsek is the most comfortable and functional quilt that I have used. It is well-designed, durable, and conservative in its temperature rating, such that it really stands out amongst the competition. It has exceeded my expectations for warmth, comfort, and reliability. *I listed the origin of my quilt as a Pro and the expense as a Con, understanding that they are directly related. When I purchased my quilt in May 2016, all production was done in the USA. Katabatic Gear now offers… Full review

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

Wilderness Experience Latok 1

Thirty-four years later the bag is in excellent shape. Now November 2018...Highly Recommended. So I bought this bag back in the early '80s when I lived in Minnesota as it was rated for -20 degrees I believe. Paid $220 for it new then from Midwest Mountaineering. Slept in my Chevy Van for awhile during -20 degree winter and this thing kept me comfortable.I'm not a climber or anything—just like good gear and to go camping occasionally. Decided to take this thing out of storage and air it out some. Full review
