Temperature ratings are intended as a guideline to help you compare products, rather than a guarantee of warmth, since many different factors contribute to your comfort while you sleep. Backpacking bags are typically rated for temperature according to an independent testing protocol—currently International Organization for Standardization (ISO) 23537, though some older items followed European Norm (EN) 13537. Testing is based on a person wearing one base layer and a pair of socks, sleeping on an insulated surface with a minimum R-value of 5.38.
Each bag then gets 2 ratings: the Comfort rating is the lowest temperature at which the bag will keep the average "cold sleeper" comfortable, and the Lower Limit rating is the lowest temperature at which the bag will keep the average "warm sleeper" comfortable. Some brands determine their own temperature rating by aligning to the Comfort rating for women’s bags, to the Lower Limit rating for men’s bags, or somewhere in the middle for nongendered bags.

Excellent sleeping bag
2 years ago
I took this with me to Nepal for some spring time trekking and the bag never disappointed. I really like the extra insulation around the feet and the W.A.R.M feature as a side/front sleeper. For the lightweight-to-comfort ratio I think it would be very difficult to find a better sleeping bag. My only criticism is that occassionally I would wake up in the night with a cold back as I'd shift positions, however, I didn't use the connector straps so I imagine this would not be an issue if they were used.

Disappointment
2 years ago
The bag was great at first use. Nice and fluffy. It felt like I finally found a sleeping bag that was actually good. It makes use of some smart designs to save weight, like less filling on the back and more on the chest, since the filling on the back normally gets compressed when you sleep. But when sitting upright or when sleeping on the side like it's 'w.a.r.m.' feature advertises, this feature turns into a drawback as the l sparseness of the filling on the back is definitely noticable. Unfortunately, a few months down the road, all the down in the first compartment on the chest disappeared. It somehow moved to the same level compartiment on the back. I mailed Thermarest about this but never received a reply. :( Loose stitching is another issue, especially when it's the stitching that holds the internal compartment walls. How do I fix this myself, since Thermarest doesn't answer?

Good Bag

This bag is perfect for backpacking. I used it in the Canadian rockies good for summer but may need another layer for spring and fall as it is cold in the mountains at night. Packs very small and is lightweight.

My new favorite sleepingbag
2 years ago
I bought it a year ago and have tested it in more than 30 nights in all seasons, different weather hiking, biking and camping. Here is why it is my new favorite sleepingbag: 1. The wider cut adds so much comfort. Compared with typical mummy bags this has so much more room. This was my main reason to switch bags, and I wasn't disappointed. 2. The straps on the back are a gamechanger for me. Having a connection between sleeping bag and pad makes it not only easy to handle (I carry the combo around in camp if necessary) but makes my sleep much more calm. 3. Despite this bag being a more comfortable sleepingbag than most, its weight is still reasonable light with 800g in my configuration. 4. Thanks to the hydrophobic down I didn't need to decide between down (comfortable, light, long-lasting) and fiber (better moisture handling). I think this material will take over the sleepingbag market soon. 5. The zipper doesn't get stuck. 6. The whole sleepingbag, the packsack and the stuffsack are all made very well and of trustworthy quality. 7. The insulation is perfect for me. I'm very hot-blooded and can easily use it down to -5 °C, but more importantly it's not to hot in the summer (unlike most of my previous sleepingbags). This is highly individual though, as everybody should know. Here are a few things that could be better, or a problem for others: 1. The bag has less insulation on the back. You really need to either use the connector straps or sleep still on your back to preserve insulation throughout the night. (This is why the bag can be as light as it is, and I knew this before ordering, but it might not be clear to everybody). 2. I wish there were longer connector strips. I have a wide pad (64cm) and it's obvious that the straps were designed for much slimmer pads. It would be nice to have longer straps. I would even be happy if I could order them. 3. My wife has bought a Questar too (smaller size, but with more insulation) and the stuff- and packsacks are hard to distinguish (only the accent colors of the straps differ slightly). It would be easier for me if they would differ a bit more.
