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.

Perfect Companion for Chilly Nights!
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.

Very Comfortable Sleeping Bag
The most comfortable sleeping bag I've ever owed! Roomy for a 6'2" guy who likes to sleep on his side.

READ the Temperature rating before leaving a review
The COMFORT range on this sleeping bag is 32°F/0°C. So, that means that your average person will be comfortable at those temps. Simply put, this is a 3-season bag. If you're looking for a 4-season bag, then do your research and buy a bag that is a rated comfort level for subzero temps (Polar Ranger). This is an awesome bag for what it is designed to do. Don't buy a bag with clearly defined ratings, expecting it to perform differently... And then give it a poor review. I own 6 Therm-A-Rest sleeping bags and 2 quilts, and they all perform as rated. I do 95% of my camping in very cold temps and these bags have performed to standard.

Pretty good with room for improvement
I like this bag very much, I used it for almost a year non-stop on a long-distance bike tour and was super comfortable in 99 % of the nights. I do have to say that it is losing a few feathers that are poking through the fabric and the downs are not perfectly distributed/ some light shining through in some places. In the colder nights (the coldest being around -4 °C) I did have to wear socks, thermo underpants and a fleece in order not to freeze. But since the comfort temp is stated at 0 °C and -6 °C is the limit, I think that's pretty fair. The fabric feels super soft and comfortable and I'm a huge fan of the Synergy Link Connectors. I used the bag with a Trail Pro mattress in regular size, but recently upgraded to a NeoAir XLite - unfortunately I didn't check the width of the Trail Pro (53 cm) and ordered a large XLite with 64 cm. The connectors are way too tight with this one and I'd be afraid to tear the bag if I slept in it with the wide mattress attached. I don't know why Thermarest doesn't offer longer straps as an aftermarket option, since it's a bit pointless to offer this kind of feature (which again, I'm a huge fan of in principle), but then make it incompatible with wider mattresses of their own product line.

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!
