Mountain Hardwear Spectre SL 20°

Warm, light, packs small, feels small, and is noisy. it is a nice bag for 3+ season use. Likely due to the laminate, it gets damp in below freezing weather; using a vapor barrier liner takes care of the problem. I find that it is very confining in the shoulder area when fully zipped. The sleeping bag makes a lot of noise when shifting around or rolling over. I can't speak to its durability since I have only used it for no more than 20 nights in my five years of ownership.

Zpacks Classic 20° 900 Fill Power Down

This is an ultralight three-season sleeping bag (20 oz total). It works great during warmer nights unzipped and open as a quilt. It can be zipped up for colder nights. Zipped up, the fit is expectedly tight. These 900 fill bags come at a premium price. This review is about my Zpacks ultralight 900 Fill Power Goose Down Sleeping Bag - 20 deg Long. I have only used this for one summer/fall season (about 6-7 outings). When reviewing sleeping bags it always seems appropriate to note whether one is a… Full review

Big Agnes Lost Ranger 15°

Plan to take it on the AT in the spring.For use in spring and fall. I DO recommend this product. I'm 6'2" and 215# and purchased the Long bag. I have slept in the bag just below freezing. Stayed toasty and warm wearing long underwear. It's packable and easy to get in and out of. I move around a lot...no problem. Love the Air Pad in the bottom sleeve as it keeps me and the bag on the pad and off the ground.   Full review

Marmot Sawtooth 15

Overall this bag is amazing. It is lightweight (1.1 kg), warm (I haven't tested it in its low point though), soft, with comfy materials. I bought this bag after searching online for a good down sleeping bag. After a good recommendation from friends I understood that Marmot has great products in this field. The Sawtooth is -9 deg C. and it weighs 1.15 kg. This bag has the best price in its category. Most of the comparison I made was versus North Face, but their bags were more expensive comparably… Full review

Feathered Friends Snowbunting

This is an outstanding down sleeping bag that will last a long time. It has very high quality down, craftsmanship, and other materials. I've had my Snowbunting for about 25 years. I believe it has lost a small amount of loft, but I still use it regularly.  Because the down can be moved from top to bottom and back, it is very versatile. If you buy one, make sure you are OK with the interior capacity, because it is expensive and will last you decades—and you'll be stuck with it. Some may find the… Full review

MontBell U.L. Spiral Down Hugger #1

Tucking into this bag is akin to snuggling up to a cloud. The -15° rating is no lie, and it easily packs down smaller than a milk jug. This is a super lofty bag with nicely baffled zippers and entrance and a soft, brushed material that has held up to the few snags I've managed to put it through over the years. The stretch of the spiral baffles is a plus for us fetal sleepers, or even sitting cross legged. Everyone I've shared my tent with has been jealous of its obvious coziness and I can sleep… Full review

Big Agnes Lost Ranger 15°

This sleeping bag is light and versatile. It is useful in warm to cold weather. This bag has performed well over the last year. I am a Scout leader and use it every month. During the hot summer months I sleep mostly on top of it. Recently I took it on a week long trek in the mountains. With the DownTek down in it, it stayed warm when ground moisture got one side of it wet. The bag dried quickly draped on top of the tent. It is very compressible making more space for things like food in the pack. Full review

Sierra Designs Men's Backcountry Bed 800 3-Season

I'm a bigger guy, and never slept well in a sleeping bag...until I got the Backcountry Bed. I have two sons in the Boy Scouts and have spent my share of evenings in a tent/hammock. I'm a bigger guy, approx 5'10" and 240 lbs. I find most mummy bags constricting and have struggled to get a good night's sleep. That is, until I recently tried the Backcountry Bed by Sierra Designs. We were heading out on a 4-day, 42-mile hike and I was determined to find a quality bag that's comfortable...and boom, I… Full review

Patagonia Hybrid Sleeping Bag

The Patagonia Hybrid Sleeping Bag is an “elephant foot” style bag designed to minimize the weight a climber carries by insulating only the bottom half of the bag and relying on insulation already required (a jacket) to keep the torso warm. The combination of high lofting 850 fill traceable down, impressively constructed baffles/footbox and 1.2-oz 15-denier 100% nylon ripstop upper (the same fabric as their famous Houdini wind shell) makes for an incredibly packable and warm night's sleep. This… Full review
