    1. 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

    2. 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

    3. 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

    4. 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

    5. 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

    6. Customer Review

      very comfortable , packs well. have not used outdoors yet but I am sure it will work great,It is like sleeping in your bed at home sleeve to hold sleeping pad is a nice would be nice if it had a strap to hold foot end on sleeping pad also on Sep 21st 2015

    7. Customer Review

      I really like this bag! I have used in both in a tent and hammock. It is very comfortable not only from an ergonomic standpoint but also temperature control. Get hot simply slip your feet out and fold the quilt down. Cold snuggle down in and you are toasty warm. Last November while camping the temperatures dipped below 20 here in Michigan and I was warm all night long. I tend to move around when I sleep and really like the "range of motion" this bag allows, as traditional mummy bags have always made me feel a bit claustrophobic. I will never go back! I would and have recommended this bag to everyone who is looking for a great nights sleep! on Jun 11th 2015

    8. Customer Review

      This bag is great for those who hate the idea of sleeping in a mummy bag. I am a stomach sleeper and this bag allows me to be comfortable and warm. I worried there would be drafts at night as I tend to roll in my sleep but after a few cold nights in this bag the only draft I felt was when my foot popped out the bottom while I was sleeping. I also love being able to keep my sleeping pad secured in place throughout the night. While this bag isn't for everyone, it certainly allows me to sleep comfortably and warm even in the backcountry. on Apr 12th 2015

    9. Customer Review

      These sleeping bags are awesome, I've never used a bag so light and warm throughout 3 harsh seasons. I highly recommend this bag for anyone who loves backpacking and being comfortable! on Oct 22nd 2014

    10. Customer Review

      This sleeping bag exceeding all of my expectations and is hands down the most comfortable sleeping bag I've ever used! I just got back from a three day camping / mt. biking trip in the North Fruita Desert and before I used it I was skeptical that this type of bag would keep me warm enough (as I've never seen anything like this before). Not only was I toasty in this bag but the best feature is the freedom and range of motion to move around and get comfortable. It literally felt like I was in my bed at home under my comforter and this is something that you cannot get from a traditional zippered mummy bag. Another thing I loved is the ease of getting in and out of the bag due to its large opening and lack of zipper. As an experienced camper and backpacker I highly recommend the Backcountry Bed and commend Sierra Designs on creating an innovative design that makes the mummy bag obsolete in my eyes. on Apr 13th 2014
