Why We Like The Questar Sleeping Bag

Therm-a-Rest packed the Questar Sleeping Bag with the most innovative features for perhaps the comfiest camping experience of your life. Down insulation keeps the bag light and lofty, and Therm-a-Rest treated the down with Nikwax to retain its lofty warmth in moisture-riddled environments. Thermacapture seams reflect your own body heat back to you for extra warmth without adding weight. Therm-a-Rest also added removable SynergyLink connectors so you never slip off your sleeping pad again, and the Toe-asis footwarmer pocket rapidly warms numb toes.

Great backpacking bag

Great lightweight down bag. Was warmer than expected and held up to its temp rating. It has a few more features than necessary but parts are removable. Lots of room inside for side sleepers like myself.

Update to my initial review on 07/02/23

After waiting 3 months (the entire summer) for a repair to my brand-new sleeping bag, Therm-A-Rest finally sent back the bag, saying it had been fixed. However, the tear in the sewing was still there, untouched. They basically kept my bag for 3 months and re-stashed it in a box (not even in the storing bag) without looking at it. What I was considering to be a bad luck when I bought this bag turned out to be a real lack of professionalism from a company that "has a very robust warranty and stands behind [their] product". If you are searching for a high-quality product, I can only recommend going somewhere else.

Love /hate this bag

Been using this bag for a year now. Warmer conditions it’s fine. But anything close to 30° or lower plan on freezing. I always have to add a liner and layers of clothing to stay warm. You can take a flashlight and see the down is not evenly distributed or none in some places.

Best Bag

Went on 35 days of wilderness canoe trips covering 500+ miles of Canada this summer and couldn’t have asked for a better bag. Temp regulation is great, when it’s hot, doesn’t feel too hot, when you’re hypothermic, this thing immediately warmed me up. Bag dries quickly when damp. Truly couldn’t have gotten a better bag, little pricy, but can tell this will last me a long time.

Great bag

Super cozy and warm, zippers work quite well, and plenty of room for your feet. 10/10 would recommend.

Sliced bread has some competition

This is without a doubt one of the easiest reviews I will write. Pros: The fabric is as smooth as butter making a lovely nights rest! The bag itself is plenty toasty (lowest I've taken this bag to is 28 degrees) Plenty of leg room to stretch out a bit while the bag is fully zipped repels a bit of water (single wall tent unfortunately drenched me but hey, I stayed dry in my bag at least!) and best of all packs down to about the size of a 32oz Nalgene bottle! Cons: None at this moment! Maybe the fact that I didn't get the 0F bag? Highly recommend this bag!

Pretty good overall, be mindful of the temp ratings

Overall this bag is pretty good, cut is very comfortable and it's nice how it stays on the pad. Although I think it sleeps a little cold, and I sleep on the cold side anyway at 5'10" 135 and with the roomy cut there's a lot of extra space in there and for me I'd say it's comfortable down to about 40-45 with an x therm pad and long johns and a puffy and hand warmers. So at 20 or even 30 I think it'd be pretty miserable for me at least.

Love it

I own the Hyperion, which is great, but with the ul'ness it's not as easy to us. I love this is still light but full zipper foot box and a little roomier. Unless I have to go ul, this will be the bag I grab for most my trips.

Hot and smelly...

First off, the straps are a pain with the wrong pad. They don't work well with a Large Uberlite very well. They did work with my old Pro Lite 4 and my old model original NeoAir. Overall, this is a good cold weather bag. I took it out in the upper 30's on the first two nights and I was hot and ended up unzipping it all the way and using it like a quilt. Before I did that, I couldn't get comfortable. I was hot and sweaty in the bag and then cold and clammy out or with it unzipped. Now the bag has that sweaty down smell. - BUT - I have been on in 28 degrees and it worked great. Maybe I'm just a really hot sleeper. I'm 6'0" and 250lbs and I fit in this bag zipped up with plenty of room to sleep on my side.
