Mont Highland Hydronaute XT -10ºC

The Mont Highland is a lightweight alpine bag for cold weather. This bag has been excellent for the wet-cold nights in the Tasmanian mountains and the dry-freezing nights in the Himalaya. It is well designed and great for those trying to cut weight without skimping on warmth. WarmthI have found that this bag lacks any sort of draft or cold-spot. Mont really went overboard with the double draft tube and lack of foot zip. I only bust this bag out when it's going to reach freezing or below. The "toaster… Full review

Mont Helium 300 -1ºC

Quality lightweight sleeping bag. Best for warm sleepers and can be used below its -1°C rating sleeping in thermals and using a bag liner. Perfect three-season bag in Australia. I bought this to replace an old Paddy Pallin bag and have used it three times. The main reason for the purchase was the small size, light weight, and claimed warmth—the Mont is about 1/3 the  size and weight of my old bag. The bag is used for bush camping with most of my walking done in winter within three to four hours… Full review

Mont Helium 300 -1ºC

The Mont Helium 300 is a fantastic, lightweight, three-season bag. It's very compressible and light for such a warm bag. This bag has a full hood and with good layering you can take this into a mild winter's night, and contains 300g of 800+ loft white down. The Mont Helium 300 is my three-season bag for wilderness guiding in Tasmania. I am typically a warm sleeper, but with the temperature swings we are prone to here on the island, it is good to have a versatile sleeping bag. Construction:I own… Full review

Katabatic Gear Palisade

Fantastic! I used an unzipped regular Marmot Spire down bag for years, and by necessity, it was a bit overkill on warmth. The hood was often in my face, even though I bought it to match the side I tend to sleep on.  This quilt is a way better concept. No hood in the face, down on top, instead of compressed below (or in my case, wasted in unnecessary width, when spread out). I've been using the quilt for three years, many nights per year. It's super well made. Very cozy at its rated temp, when… Full review

The North Face Men's Superlight 0

When I bought my NFSL in 1974 it carried a lifetime warranty from NF. I sent the bag to NF in the late '70s for repair and it was returned cleaned, refilled, and repaired. Amazing! I still have this bag and only "retired" it this year. A 45-year run for a $106 investment. Hard to beat value that has been one of the best pieces of gear I've owned.  I've always stored this bag in a large laundry bag to help keep the loft high. At the end of the season I would wash the bag by hand in a bathtub. Since… Full review

The North Face Men's Superlight 0

By today's standards it is not super light, but when it came out it was. Dacron weighed about 9# vs. about 3.5# for the North Face Superlight (NFSL). In 1968, I had used a Dacron 88 bag for high country experience and never got a good night's sleep. Froze once—learned lesson. In 1969, bought the NFSL from a local sports store that did rental toward purchase and they suggested it had maybe two more seasons left to it. Bought it for the astronomical price of $95 (New it was $299. At that time I… Full review

The North Face Dolomite Double Down 20F/-7C

Roominess, warmth, possibility for snuggling. Late May Algonquin Park trip. It was my wife's idea to change it up from individual bags to one, double bag. I was skeptical. May in the park can see overnight temps close to freezing and I always associated double bags with fair-weather, car campers. I was wrong. Quite wrong. Not only did this bag keep us both warm, it offered more flexibility in sleeping position and actually lowered the overall weight/bulk of our pack (canoe camping). Full review

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
