Best 40 Degree Bag in my Honest Opinion, Great for Side Sleepers as well...

I absolutely love this sleeping bag... Was able to get it for $89 as sometimes it drops from a usual $149 or $169 so keep your eyes peeled and be patient if need be. Anyway, NatureHike has become my favorite go to Camping Gear place. This Sleeping Bag packs up super small, it's very very light like around 2lbs fully packed. Also, it's TRUE to it's words it will be warm down to 41 degrees in underwear. I have a $300 plus sleeping bag, Nemo, for 25 degree weather and hadn't ever had any other bag. Wanted a bag that I could use during the Summer and Fall that was LIGHTER and took LESS room in my backpack. This one is it. THE BEST PART is that there is plenty of room for SIDE SLEEPERS. I can turn at night and be totally comfortable. So, if your looking for a bag that is WAY more comfortable than a MUMMY Bag but don't want to pack in 6-10lbs for your favorite Car Camping Bag, this honestly should be your go to bag... Its is for me.... I'm ALSO going to use it as a QUILT this weekend as my NEMO bag is only rated for 25 degrees and I'll be in Snow and under 20 Degrees so this bag will be a blanket on top of my NEMO. Read more

Warm, light weight and compact

Got two for my friends for a backpacking trip, it was about-4°C at night, and they slept comfortably. Light weight and compact. Read more

Good bag, used on multiple trips

Used on multiple trips now. Very happy with size as there is room to move around. Like the packed size as well as it saves space in bags or packs. Bag starts to get cold when temps hit 45. Have not been colder and do t really care to test. Needs more fill. Using same branded sleeping pad. Read more

Good value

I've experimented with this NatureHike brand on their Vik tent and now this sleeping bag. The one person tent is awesome. Now for this bag. I feel like a gear nerd and like trying something new on every outing. I have not used the bag yet outdoors but as rated 30-40 deg. f I feel like I can for Cascades summer nights at 6000ft elevation. As a 5'10" 210lb dude I needed to order the larger size to be able to roll around in it. It lofts up nicely with a hood and a ykk zipper. The rectangular shape allows for stomach sleeping. The fabric is light and the fill looks good to provide the temp rating. Not quite being an 'ounce-counter' but conscious of it, Nat Hike built the compression sack w/ only 3 straps instead of usual 4, smartly cutting weight. Excited to try it out in a few weeks. Used in now on a 2 night summer outing in central OR mtns, temp prob got down to high 40s-f and I think it was the best night's sleep I've had out in the woods in some time! It's light, compresses small and hase a hood, unlike a quilt. Read more

Best affordable down bag you can buy

I’m pretty sure you can not find anything comparable for the price. This bag is hard to beat. I have used it down to 42F and was perfectly comfortable and toasty. I think maybe it could go down colder and perform well, I’m thinking 30. The loft is excellent and seems to stay evenly distributed. This is literally a fraction of what my other bags cost. This is my first bag since I was a youngster that is not mummy shaped. I slept so crazy good in this bag, I’m not sure if it was this bag or I was just beat down from a long hard day. Either way, my new favorite. It comes with a compression sack! packs very small. Just remember to take it out and hang it up or buy a large mesh sack for long-term storage. Read more

Great sleeping bag for the price!

Very comfortable, warm, and lightweight. Great bang for the buck. It has plenty of room once you zip it up to move around and turn on your sides. Highly recommend. Read more

Sleeping bag

This is a light bag, overall construction seems good. The temp rating is off though. Dimensions are correct, I'm 6'4" and 211 lbs and I fit with room to move around. Read more
