    • It Works Well, Snug as a Bug!

I studied sleeping bags for literally months before ordering this one. I was torn between versions that were $500-$700 for the lightest and warmest, but I simply couldn't find an excuse to warrant spending that much on a sleeping bag to shave a few ounces. Down to the wire before my camping trip in the autumn mountains this past weekend, I finally decided to order this and a quilt style to see which I liked better. This bag won hands down and I am returning the quilt. This bag packs small for the temperature rating and is relatively lightweight. It fit easily in my backpack and fluffs right up when removed from the stuff sack. I got inside to test it indoors and immediately started sweating. It has plenty of room for me to move my arms and legs when fully zipped and works when side sleeping as well, although the mummy head section is annoying when side sleeping. The best part is how warm I was at 15-20 degrees F. Sleeping bags are rated for survival - comfort level is about 20-degrees higher. I sleep cold and like warm blankets and found myself comfortable with just a base layer on in this bag. With a liner, it would be even warmer, but I don't want to backpack with that unless I really need it. I was terribly thankful for having this bag when everyone else was cold and filling their sleeping bags with hand warmers to stay warm! The down stays where it should and the baffles inside do a great job keeping warm air in and cold air out. The zipper didn't snag even once and is quite sturdy. All said, this bag is everything advertised and I feel it was a great investment in gear. ... show more

    • Great insulated bag that packs small
Color: Black/Clementine Size: Long
Review Image by ryan ferguson ryan ferguson
This is a good ass bag. Ive had it for a few years now and it shows as the hyke and bike is rubbing off. Looks like a trash bag but well worth the money. She stays in the closet between events hung up. Stays pretty stinkin warm. Ive had it in -10 to 90° F. Sleeping pad helps and base layers help in the cold. It has replaced my military bag completely. Im so use to lending my gear out that this does the same job in a much smaller package. I do pack a bivy to put it in and have not tested it out for being water proof and don't intend to if i can help it. Definitely suggest the XL. It gives me enough room to move around and not be bothered by the mummy design that i dont care for. Pros Warm Packs down super small. Fits in my eberle stock bag. Durable zipper Cons Sometimes insulation shifts and leaves thin spots for cold buns. Sounds like a trashbag when you move around. This is a nice bag, get a nice sleep pad to go with for no worries. Go XL and get a wide pad. Well worth it. Youll still be light and you can sleep at night. ... show more

I am a purchasing consumer, and my review is not based on a free review sample. I am not getting any kind of compensation for posting these comments. Completely happy with this bag. Recently went on a 14 mile backpacking trip to Yosemite, camped at about 6500 feet with some light snow fall that dusted the ground a couple days prior. Second trip was a nice car camping trip in the Santa Cruz mountains. Temps at night ranged from mid 20's to upper teens (F). Beneath me I have a thermarest Z-lite "egg-crate" and a Neo-air inflatable pad. As a 100% side sleeper I need extra padding for my hips and shoulders. Clothing was thin dry-release base layer and wool socks, nothing more. I also have a cheap costco down quilt that I spread over my foot/ legs mainly to try and keep condensation off my feet. I am a COLD sleeper too. Which by itself isn't bad, except when I get those chills at night it makes me want to pee!! totally sucks, I'm like a little girl in this aspect. Which is a royal PITA. I slept warm, cozy no problems with condensation or anything like that. There was always a warm pocket of dry air around me. I am 5-11 and 195 pounds, average build. The regular length was a PERFECT FIT. At no point did I feel constrained in this bag. Shoulder area is roomy enough for me as a side sleeper to roll around from side to side. I was able to pull the hood over my head no problems. LOVE the non-shock corded draw string, nice touch there guys!! Love the safety orange and black coloration too. Its easy to see things against the orange. I put my gloves and wool hat inside the bag to keep them warm... but I never needed them in the night. Compacts down very nicely too with a great stuff-sack. Packed down and compressed its only a little bigger than my ~30F summer bag, a suisse sport trekker from big-5. [Nov 26, 2017, UPDATE] Just finished another backpacking trip at Point Reyes california. Temps got down to low 40F at night. I was warm and toasty all night with nothing more than dry-release base layer clothing, thin gloves and wool socks. For this trip I did not use the extra down quilt that I used above during my Yosemite trip. I love the rigid-cord draw string hood!! I prefer this over elastic shock cord. I have no regrets at all, I would buy another in a heartbeat if I needed to replace this one. ... show more
