I normally wouldn't write a review of a product unless I immediately disliked it or I've given it enough time and uses to firm up my feelings on it but this sleeping bag really impressed me. From its weight, packability, design and perks, this has, thus far, been a well thought out product. I've taken it out on 2 excursions. One was a chilly night, the other was a rainy and chilly night. Both nights topped out at just above freezing and for both nights I was warm, comfortable, dry and attached to my Big Agnes Insulated Air Core Ultra pad. Very impressed with the zipperless design, placement of fill, build quality, pad sleeve and venting options. Price is also better than similar ultralight bags. Hope it lasts. Very happy with my purchase. Read more
I bought this on a hunch that I would love it. I had still been using my bag from literally 20 years ago, a 20° down bag from EMS that is still so warm and lofts fine — but it's a mummy bag, and I tend to flip between left and right side all night. This bag is heaven. That "blanket" flap is wonderous, feels like tucking yourself perfectly into a blanket. Never too tight. Attached to my pad, I could flip inside the bag easily, or throw an arm or a foot out like the photos show in order to cool off. I was worried about being able to sleep on my right side (facing the left side of the bag) and still breathe comfortably, but even that turned out to be totally okay and easy. I haven't yet tested it down to lower temps but last night was cold and I was overheating in the bag. Given how lofty the bag gets, I imagine it's pretty warm. It's light, well-designed, and inexpensive. I don't feel mummified in this bag. So much nicer than zippers. Make sure to check the specs on the maximum pad width. The regular can't take a 25 inch pad like the Nemo Tensor Wide, so I had to get the long version of this sleeping bag. But it's so light that it just doesn't matter. Read more
Super comfortable and warm paired with a good sleeping pad. Love that it packs small and has the storage bag for when not in use to keep it fluffy and not compressed. Read more
I own lots of sleeping bags, multiple western mountaineering, feathered friends, marmot, and some of the cheaper brands such as klymit and Hyke and Byke. I am a gear junky. And I love this bag. It provides more internal room then all my other bags. There is no zipper and I actually find that to be more comfortable. It can let in a draft if you roll around some, but at least you can roll around. If you suffer from claustrophobia this bag may help ease your way into using a mummy style bag. I also found it to compact better then all my other 20 degree bags, it is super light, super compacting, and a great 3 season bag. Besides the lack of zipper there is also minimal down on the underside of the bag. Since sleeping on down compresses it and makes it useless this shouldn't affect the functionality of the bag. The removal of this down allows for a more smaller cubic volume when packed. Sierra design also has great warranty and customer service. Read more
OMG! When I unboxed this sleeping bag and crawled inside, I knew it was exactly what I had been looking for. I have been trying to find a lightweight sleeping bag for backpacking without spending a crazy amount of money. I'm claustrophobic enough that all the lightweight bags I've tried are too tight for me. I always had to keep them unzipped around the chest to get enough room to move around. This bag gives me plenty of room to move my arms around or even sleep on my side, while at the same time keeping me warm. It feels just like being in my bed and pulling a comforter around me. The design of this bag, including the foot vent, allows it to be used in several different temperature ranges. I will be taking it on a 5 day trip next month where the temperatures could be down into the 30's. So I'll be able to update this review as to the warmth of the bag following that trip. Update: I spent five days in the backcountry of Wyoming last week with this sleeping bag. The temperature dropped to 30 degrees every night, and even 25 degrees one night. It was PLENTY warm with only a foam pad under me. The weight was good for backpacking, considering the economical pricing. I will probably look for a smaller stuff sack so it doesn't take up as much space in my pack. Read more
This sleeping bag is wonderful! It’s very lightweight and the down makes it very packable. I love the zipper free style and the secret foot vent at the bottom makes it easy to get comfortable. Hard to turn in if you toss a lot, but that doesn’t change my mind about it. Easy in and out and very very very warm! Read more
The Long version appears to lengthen the skinny lower leg area instead of the wider chest area. This results in unnecessary leg confinement. Top area felt great. The result is a really neat, roomy upper chest area, but confined/claustrophobic legs. Bummer. Sticking with my Spoon shaped bag from Nemo. Sierra Designs should make this zipper-less bag spoon shaped. Read more
I love how warm this bag is! The first night I used it the temperature dropped to 30, I was nice and snug the whole night. It's fluffy which I like because it feels more like an actual blanket like that. I also like the "no zip" feature. This featured allowed me to wrap up in the sleeping bag similar to how I sleep at home. My only complaint is that the bag smells HORRIBLE. Like so bad that it kept waking me up throughout the night. I need to wash it, dry it, and let it air out some more. My dad got the male version of this bag and his did not smell at all. So it may be a 50/50 chance of getting a bag that smells. Read more
