Naturehike Ultralight Backpacking Down Sleeping Bag for Adults, 650 Fill Power Sleeping Bag for 42/52℉, 20oz Compact Lightweight Sleeping Bags for Hiking Camping 3 Seasons

Good bag for hot weather backpacking. I like how small it was - I shaved the weight of the compression sack and used a drawstring ditty since it was small. I used it for my 4 night backpacking trip INSIDE the Grand Canyon where low temps were 50-60deg. At ~50 degrees, I was colder. Had to wear extra layers. When I slept at the North Rim (low 30s), I used my 25F bag that I shipped across the canyon. Fit the canyon interior needs. Note I used an insulated Nemo air pad (R 4.5) with a thin aluminum foil sheet underneath that also reflected heat. So your mileage will vary depending on how warm/cold you sleep and how well your pad is insulated. I’ve just pulled it out to use it for couch naps. For insurance, you can carry a SOL Escape Lite Bivvy (~5 oz) and slip that inside the sleeping bag to extend warmth. (Don’t get the imitation brands). Be sure to slip it inside so it reflects and avoid condensation.

So glad I got that! If you are a woman of a certain age you know the horrors of an overly warm sleeping bag. I use this for winter camping in Maine, and although I wouldn't recommend that for someone not having hot flashes, it worked great for me at the time!

I was very nervous ordering this item. I'm always a bit suspicious of the quality or reliability of these Chinese brands, but I've gotten to check out a Naturehike tent before, so I was hopeful that this bag would be a good purchase.I was in the market for a small and light summer weight bag, not a mummy style, and preferably down. This bag ticked all the boxes. The included compression sack can get it squished down quite small - about the size of a nalgene - and the bag was comfortable and seems to be of good quality.I feel that the 50-ish degree comfort rating is pretty accurate. I've used this bag on two camping trips now:On the first, I was car camping in a tent, and nighttime lows reached about the mid to upper 50s. I used this bag essentially as a quilt - unzipped and laid over top of me - and I only wore a tshirt to bed, and I was very comfortable, sometimes almost too warm.On the second, I was backpacking and spent the night in an open 3-sided backcountry shelter, and nighttime lows reached about 50 degrees or maybe a bit under, with heavy rain all night cooling things down a bit further. On this occasion I used the bag zipped up, and wore long underwear, warm socks, and a hat to bed. I also had a thin fleece blanket in case I got too cold. I was very cozy in this setup - again, almost too warm at times. While I did use the blanket to be truly cozy, I pushed it off several times throughout the night and was still perfectly warm.In terms of complaints, I do have a few issues with this bag. For one, while the bag is a true rectangle and gives my legs enough room to move (unlike mummy bags), it works out to be quite tight around the upper body. I'm not huge - 5'3 with moderately wide shoulders - and if I had my arms in any position other than wrapped around me the bag felt quite tight. Not a dealbreaker, but not ideal. I also find the placement of the cinch cord less than ideal. If the bag is used unzipped, then the toggle is located right in the middle of the top edge. It would be preferable to have this toggle located on the same side as the zipper, although the current position does allow the bag to be cinched, for example, on the front edge but not the back.Altogether I'm very happy with this bag. It does the things that I wanted it to do, and it does them pretty well. Because it's so affordable, it also provides a viable point from which to modify the bag to your specific needs. At some point in the future I may try modifying the bag to be a more traditional backpacking quilt: closing the footbox, adding loops for pad straps, and moving the cinch toggle over to the side. The low pricepoint means that I wouldn't feel bad making these changes. All in all a great bag!

This is a very compact sleeping bag. It stows away easily back into the bag after use. I am 6 ft tall and have no trouble fitting into the sleeping bag. It is easy to get into and I enjoy the blue color.

very light weight

We got the 32 degree one because the 40 degree one just didn't really make sense to get. It is super comfortable and super warm in my opinion. Lots of room if you are a side sleeper like me!Can't beat it for the price and weight (~1.7lb) to warmth and comfort ratio in my opinion.Love that there is slightly more padding on the top part than the bottom part too, since once you are laying on it the bottom of any sleeping bag gets too compressed to offer much insultation/R-value).On warmer nights I use it like a quilt, basically just half zip it so the bottom is zipped and the top just drapes over me, it's plenty wide that it doesn't come up on the sides but is easy for me to stick an arm or leg out if I'm hot)We have the One bag from North Face, and although they are super warm, they are HEAVY! I also don't LOVE the mummy style of it, it is great for COLD, but anything over 35 degrees and I start to feel trapped and hot but if I unzip partially then it doesn't stay on me.) Still planning to use that bag for colder nights, but this is great down until 37-40 degrees in my opinion.ONLY complaint is that I am SHORT, and this bag is soo long, I wish they would have had a short or even at least a regular length one, the warmer weather one is shorter, but this one is super long so I have a bunch of dead empty space on the bottom by my feet. Kind of feel like I could save a couple ounces of weight if it was shorter too. Optional quilt straps would be nice also in my opinion, but since it isn't a true quilt, I feel like I can't really complain about it! (ha)Would definitely buy again and would definitely recommend to buy to anyone looking for a great spacious bag, especially for the price point!

The bag looks well made, with solid stitching. The zipper opens & closes, with ease. I like that it packs down very small, taking up little room in my pack, but lofts up decently. It will be a good addition to my spring backpacking gear for cool weather.

Not worth the money at all, retuned.
