[ I bought this for future, unknown trips. My nephew immediately took it out of the box and got into it. He looked so comfy I decided to try it in my bed and now I just love it and sleep with it. It OPENS on the bottom to stick your feet out. This is why I bought it. I ca n't stand sleeping without sticking my feet out to breathe lol. So, it has n't even made it outdoors yet but the quality and comfort is excellent. I bought it used on the site and it was in excellent condition as described. Has a very nice packing bag as well with straps. This is why outdoor equipment is worth paying a premium; you really get what you pay for and I highly recommend the brand.

[ Great spring and summer bag! Super soft down and silky fabric. I love the zippers to vent, especially when my feet get hot, I can open the bottom and keep warm up top. High quality zippers with extra fill around them to prevent snags and drafts. Love it! Mesh storage bag is a nice addition, but it could be bigger.

Very comfortable sleeping bag. Great sleeping bag for side sleepers. Roomy and don ’ t feel restricted. This sleeping bag will keep you warm at 0 c, but you may want to consider a synthetic quilt or wear a down puffer jacket for cooler temperatures to keep warm.

Farnoud N.
I ’ ve been using the Questar™ 20F/- 6C Sleeping Bag on several camping trips now, and it has exceeded my expectations every time. The warmth and comfort it provides, even in colder conditions, are impressive. The fit is cozy without feeling restrictive, and the materials feel high- quality and durable. One feature that stood out to me is the SynergyLink™ connectors, which kept the bag securely in place on my sleeping pad throughout the night, preventing any cold spots. I also appreciate the ThermoCapture™ lining that effectively reflects body heat, making this bag a true lifesaver on colder nights. Setting it up and packing it away is a breeze, and it compresses well for easy storage in my backpack. Whether I ’ m car camping or backpacking, this bag has become my go- to for any adventure where I need reliable warmth and comfort.

Shane
[ COMFORT: First off let me state that this bag is not made of some super thin sticky nylon like some ultralight bags are. This very soft to the touch and extremely comfortable. I actually prefer the way it feels to my actual bed at home that we have spent thousands on. The bag lofts up nice and thick and looks very inviting and actually makes you excited to snuggle down in it for sleep. In addition, the bag is very roomy. It doesn ’ t feel constricting like typical mummy bags. If you are a side sleeper or toss and turn I HIGHLY SUGGEST YOU GET THE LONG VERSION of this bag even if you don ’ t need it for height. The main reason is that the long version of this bag is also wider in the foot box than the regular length. This provides quite a bit more comfort for those of us who move around a lot at night. Even though the long bag says it ’s for 6 ’ 6 ” people I ’ m 5 ’ 10 ” and this allows me to snuggle down into the bag and pull it over my head for warmth as well as leaving me the option to store gear in the bottom to prevent it from freezing. Had I got the regular length it would have forced me to sleep with my head outside exposed and left no room in the foot box. TEMPERATURE RATING TEST: It ’s October now and we recently had some cooler weather move in for a couple of days so I used it as an opportunity to test the bag and my new sleep pad. According to accuweather temps dipped down to 40*. I slept outside on our deck to test this bag. First I laid down a thin blanket to prevent any damage to my thermarest from splinters or such. Next was my thermarest neo- air xlite. Finally, this bag which is comfort rated to 32* when you wear appropriate base layers. As stated above, the temps supposedly dipped down to 40* and I chose to wear nothing but my boxer briefs as I figured if I stayed warm then I should have no problem staying warm to 32* with wool base layers as the rating suggest. I can confirm that the bag worked great. No issues whatsoever. I slept all night in the bag and never got cold. Starting off the night when it was around 48* I was actually too hot and had to unzip the bag. At about 7am when temps were at their low I stayed zipped inside but stayed comfortable. The biggest surprise to me was that I didn ’ t get cold feet. I don ’ t think I have ever slept outside and not got cold feet. And this is while wearing thick wool socks. Often 2 pair of them! In this sleeping bag I wore no socks at all and my feet stayed warm. This was a pleasant surprise. I now have no worries as winter progresses that this bag will do just fine in lower temps so long as I wear appropriate clothing as suggested. CONCLUSION: In conclusion, if you like to move around at night and don ’ t like a typical mummy bag this is the one you should get. It ’s very roomy and never once did I feel confined. I rolled and tossed all over the place and stayed warm and cozy. I spent hours searching for something lighter and while you may find something a few ounces lighter than this bag it will cost twice as much and will be about a foot narrower in the foot box. I hope thermarest never stops making these bags. I want to save up for the 0* version now for those really cold nights. I now have a thermarest xlite pad, this thermarest sleeping bag, and a thermarest pillow and none of them have disappointed me. At this point I don ’ t think I would hesitate to buy anything thermarest offers if I needed it because it ’s clear their gear is well thought out and quality made.

[ This is the best sleeping bag I 've ever used! I 've always had trouble with sleeping bags because they take up so much space in my backpack, but this bag is so compact and allows for other essentials to be placed in my bag. Its full sized and very warm. I like to add an extra blanket and pillow and it gets very comfortable. This is an essential to anyone who camps or travels.

[ I live in the desert, so this was perfect to test drive in 72°F Las Vegas weather. I wasn ’ t too hot or too cold, this sleeping bag is lightweight and durable. My only complaint, would be I am 5 ’ 10 tall, I didn ’ t have a lot of wiggle room. This thing is perfect for on- the- go and a good night ’s sleep wherever you are!

Goran L.
[ I absolutely dig this Basecamp bag. This bag is of great quality. I recently went on a 3 night camping trip. I have a 4runner that I am able to sleep in with plenty of room so I got the Basecamp bag to use in it. The bag is very big with plenty of wiggle room, which is important to me since I flip and flopp around at night. There is also space for the next days clothes I can keep in the bag. The zippers allow for the bag to open in various configurations.- 1°c and I was toasty warm. P.s. I sleep with two windows open that i mesh over for that fresh air feeling.

Thomas B.
[ Awesome bag. Super roomy. I like the strap attachments for my sleeping pad. It keeps it flat. I can roll around without getting tangled. I love the ability to open it on either side and the bottom to vent if I get warm. I have slept in it around 30 degrees amd in the 50's and was super comfortable. I have n't opened it to quilt yet, but maybe this will put my summer bag to rest. It packs down nice, considering how wide it is. The down is lofty and has no smell. No regrets.

[ I had my own Kelty and my kids had other bags. My son stole my bag while we were camping at Waldo Lake so I used his and I nearly froze to death. I felt so bad he had such an awful bag! I had no idea!!! So I got him and his twin sister bags that match mine and last night we slept in them and it was DREAMY. Love them!!

[ Bought this bag as a lightweight down alternative to my synthetic bag. I love this style of bag so it was a no brainer. My first test on my living room floor resulted in a 2 hour nap. I like that i have room to move my legs or toss and turn, and that you can attach 2 of them together( ill be buying another). Great bag if the mummy style bag isnt right for you.

Jjourdan
[ Just took this bag on a 12 day trip to Philmont Scout Ranch in Mew Mexico. On the nights when the temperatures dipped into the 30s, this bag kept me very comfortable when zipped up properly. On warmer nights, I unzipped the bag about 30 percent to let a little air in. The best part was that the bag is extremely light and compress down very small in a compression sack to take up very little room in my backpack and could even be clipped on to the outside of the pack without any noticeable swinging while I hiked.

[ I 've had my Kelty Galactic 30 for 5 years, and just bought a pair for my son and his wife. In my opinion this is the best bang for your buck in a sleeping bag for backpacking or camping. Packs small, lightweight, and reasonable price. It has a lot of loft and is very cozy. I sleep comfortably in it down to 40 degrees and add a liner to get to the mid- 30's, so it serves me well 3 seasons. I 've thrown it in the washer and dryer several times- just shake it out well and it regains its loft. Highly recommended!

Even gave me the best discount they could get since I was a first time customer. Will for sure keep buying.

[ I have several sleeping bags and quilts, but I wanted to consolidate my gear and find a sleep system that could do it all. My search stopped when Big Agnes released the Lost Ranger UL 0° system. So far, the temperature ratings of each bag have been accurate. I ’ ve been comfortable into the low 20 ’s with the inner bag by itself and comfortable in the mid to low 40 ’s with just the top quilt. Paired with the Rapide SL sleeping pad from Big Agnes, this sleep system is incredibly warm. I used both bags on an overnighter where the temperatures got below 20° and I slept like a baby despite having condensation issues due to poor ventilation in my tent. The top quilt was pretty damp that morning, but because the down used in these systems is hydrophobic, it was dry before lunch. If I could change one thing about this system it would be to add another zipper on the right side of the quilt. If you could make the quilt removable from the fitted sheet at the same time that would be nice too so you could take the quilt with you around camp. Other than that I LOVE this sleep system.
