Review: Thermarest Questar 32F/0C

Full disclosure, I love backpacking, but I don’t love carrying a heavy pack. I’m always looking to reduce weight as much as possible.

It’s a constant battle, and difficult to lighten the load while balancing the need for warmth and comfort. And I’m one to get pretty cold. Let’s just say you’ll often find me sleeping in my down jacket.


When I had the opportunity to test the Therm-a-rest Questar 32, I was excited to see if a person who runs extremely cold could cut the weight, without freezing at night.


This bag is a mummy shape, that has lots of room in the top half of the body. I typically am a side sleeper, and I like to have one knee bent in a “number 4” looking position. Mummy bags usually resort to me feeling confined and trapped. I found that wasn’t the case at all with this bag.

The Questar features more of a “human” shape, with a tapered width that increases in the chest area, I found it perfect for tossing and turning sleeping like myself.

The SynergyLink Connectors also kept my bag secure and centered on the pad, so the tossing and turning throughout the night didn’t result in my waking up to find myself on the cold hard ground.

The Questar’s Toe-asis footwarmer is a contoured footwarmer feature that kept my feet nice and toasty, and I found myself actually tossing my extremely thick wool socks and sleeping with naked feet. Something I definitely wasn’t used to with other sleeping bags. 


Max user height – Short 5ft 6 inches, regular 6ft, long 6ft 6 inches
Shoulder girth – 58” small, 63” regular, 66” long
Hip girth – 58” small, 61” regular, and 64” long

It also works great as a general blanket. During the colder mornings, I would wake up and sip some coffee down by the alpine lakes. Unzipped, and folded out you can keep your feet warm and toasty and toss the top layer over you for a comfy blanket!


I know color isn’t an important factor for most, but I love the green and the accented zipper colors. It’s a well put together package, that from a design standpoint is really great.


My favorite part is the SynergyLink Connectors on the bottom of the bag, which have two very wide and stretchy “straps” running across the bottom. There are three fasteners to allow you to unclip, stretch across and reclip. These were a bit tricky to clip in, because of the flat design – mostly so you don’t feel them underneath you, so I typically kept them clipped and just slipped my sleeping pad in through the bottom. It fit perfectly with my NeoAir pad.

The bag is filled with 650 fill down and has a Nikwax hydrophobic treatment, which helps you stay warm even in moisture. I like sleeping with the rain fly off, which can result in a dewy morning, and this bag kept me perfectly warm. It absorbs 90% less water than untreated down, without the negative effects of harmful PFCs.

The down insulation stays fluffy and puffs up quickly after taking it out of the compression sack. It also features zoned insulation, which maximizes the warmth and provides captured heat in the places you need it the most. Therm-a-rest’s down is also Responsible Down Standard Certified, meaning the waterfowl the down is harvested from are treated humanely. A very important feature.

Their W.A.R.M fit (which stands for with additional room for multiple positions) is implemented technology that gives the bag a roomier feel for the tossers and turners like me, without having you feel like you are an actual mummy.

I love the extra large hood design, which allowed me to fit my camp pillow inside, and helps keep the neck supported even when tossing and turning. You can also synch it down for more warmth.

The full-length zipper draft tube is perfect for hotter nights, or when you want to use it more as a blanket. A couple nights I unzipped and then used the snap at the top of the bag to clip the top layer to the side of the hood. It allowed me to separate my legs, and peak out that foot when I got too hot.

The stash chest pocket is also perfect for keeping my phone safe (don’t worry I only use it for pictures in airplane mode to fully disconnect), so I didn’t lose it in the tent.


This bag packs extremely small, and I found myself surprised at how compressed I could actually get it to be. It packs very easily, and the compression straps cinch it down to a very small size. It also comes with a storage sack to keep the down lofty when you’re not using it.

It’s not necessarily as small and light as an extreme ultra-lighter might require, but perfect for the avid backcountry adventurer looking to cut weight without sacrificing comfort or features.


This bag is holding up really well so far and I’m very confident it will withstand the harshest of beatings. The zippers are working perfectly, as they should. I often find zippers on other bags get caught when zipping, but with the Questar I haven’t had that issue at all.

Therm-a-rest offers a Limited Lifetime warranty on the bag – which have a 2 year limited warranty. They also cover you with their Better Sleep Guarantee, which means if you’re not liking it, you can return it within three months and you get a refund – no questions asked. I love that a company offers this, and stands by their customer satisfaction.

The Final Word

I love this bag, and find it to be absolutely perfect for three-season backpacking. Guaranteed comfort and warmth without lugging around a heavy bag, Therm-a-rest has implemented designs that help accommodate a more realistic “human” sleeping position, perfect for a tosser and turner like me.
