    1. Best Sleeping Bag Ever!!

      No zippers!!! Ever again!!! You can get out of it whenever you want!!! So warm and comfortable, I don't want to get up in the morning. I've had around ten different sleeping bags in the past and I can easily say that this is my favorite by far. Its big, even when compressed, so not really great for backpacking.....its great for being comfortable and warm.
      I'm 6'1" and have the long. More than roomy enough. I would probably get the regular size for backpacking, and I still may. I am completely satisfied with my purchase!

    2. A pleasure to sleep in!

      I work on a trail in Colorado and camp for most of the summer. I bought the backcountry bed and I've spent over 50 nights in it so far this summer.
      It's as comfortable as everyone here has said. The oversize comforter is great and can be fully pulled over your head if it gets really cold.

      The foot hole is great as well, I sleep warm and it's nice to be able to stick my feet out and when it's cold the foot hole doesn't leak cold air. After using it, it should be a standard feature on all sleeping bags.

      My only small complaint is that my backcountry bed gets a cold spot in lower temperatures right around my thighs. The baffling there seems to have as much down as anywhere else so I'm not sure why it happens. Anyway a very minor problem.

      A week ago I tried to sleep in a regular mummy bag and couldn't wait to get back in the backcountry bed. Bottom line: I love this thing and if they made a lower temp rated (5 or 0 degrees) I would buy another one!

    3. Dope!

      This bag is the bees knees.

    4. I love this bed!

      I bought this for a trip down to Havasu Falls in the Grand Canyon last March. I wanted to cut weight and have been eager to get one since they came out. I can't tell you how comfortable my nights were. It temps were to drop into the upper 20's so my son and I picked up warm weather bags. I got this and he got the Zissou Plus 700 / 15 Degree. Lucky the weather warmed up and the lows were in the upper 30's. Needless to say we were warm the whole night through. I was never bound up or felt constricted. I didn't want to come home to my bed. It packs up small and is light. on May 11th 2017

    5. I could not be more pleased with this sleep system!

      From way above the timberline on ten day pack trips, to down in the deserts and canyons of Souther Utah, I constantly wake up in grateful awe of the good comfortable night this product has provided me. I don't much care for those "Just got my product in the mail" reviews, because really, what do they know, but I've been packing this around for two years now, on 4 week long pack trips and a few more weekend excursions, and--- I love it! I show everyone I can, and preach its virtues, and try to share the goodness. Specifically, I love that I can role around and not get tied up in the bag, I love that I don't have to wake the person up next to me with clumsy zipper fumbling, and I don't have to wrench my shoulder trying to zip back in after the midnight drain. I love that I can straiten my arms down when Im sleeping on my back without the tube top freeze out (because my elbows get so bloody stiff all bent and bunched up in a mummy bag. ---Really folks: This system is dreamy. I'll never go back to a mummy bag unless they are embalming me for my own funeral. on Nov 8th 2016

    6. 95 straight nights of bliss(Backcountry 600)

      I am a fishing guide in Alaska. I spend the entire season out at our tent camps. I wanted a warm and "comfortable " sleeping bag. I saw this bag and decided to give it a try. 95 straight nights and this bag was comfortable; warm and durable. A very clever design system- the guides I work with took note and are moving out of their mummy bags. Perfect for a cot. on Sep 28th 2016

    7. Favorite Piece of Gear

      I hiked the PCT in 2015 and absolutely loved this sleeping bag. I'm 5'6" female but selected the men's tall for two reasons: more room inside the bed (I hate things feeling tight) and extra length for my K9 hiker (she loved it, too). For my next long-distance hike, I'm trading my tent, sleeping pad, pack and a few other essential pieces to save weight, but I refuse to trade this sleeping bag. I can't sleep on my back due to head/neck issues, so I'm predominantly a side sleeper. On cold nights, I tuck in the quilt and stay toasty warm. I often tuck my hands into the pockets and then tuck my hands under my head. Everything stays warm and draft free. (Only suggestion for improvement: make the bottom of the opening a little farther down so it's easier to throw a leg out.) It is so comfy that I sometimes use it at home and in my RV, just because I like the way it feels. AWESOME BAG!! on Sep 16th 2016

    8. Best Sleeping Bag Yet...

      My history of sleeping bags- cold but pleasantly able to stretch and feel free or warm and rigid, unable to move. As a professional in the outdoor industry, I've tried many bags and resigned myself to little/poor sleep until I was so many nights out I'd fall asleep in exhaustion. This bags solves many of those issues. I think the top of the bag is pure brilliance. When warm, toss the "comforter" top down to cool off. When in between, cover your hands but free your arms. When cold, hunker down with your hands super toasty. I liked popping my feet out the bottom, but here's the one thing that would make this bag even better (in theory, it may be as good as a sleeping bag can ever get)- I did this as I felt constrained, not hot. I get the advantages of a zipper less design, but if one could be added along the seam from the waist to the feet, or if a comforter approach could be taken there as well, I think it would be beyond perfect. I like to toss a knee or leg out of a bag/bed, which you can't do in this bag. You slide your lower body in than bundle your top as you want. Using this bag still the best nights of sleep camping I've had in years, or ever. on May 31st 2016

    9. Best Sleeping bag ever

      I love this bag! Used it for a three week Grand canyon Trip in march and it was perfect. I love the zipper less style - it is super comfy and warm. Great Idea, Great product. on Apr 8th 2016
