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.

Very Good Sleeping Bag
3 years ago
This is a 5' 6" (short) 800 fill down bag that is light and small. I like it very much. However, I was attracted to it also because of the sleeping pad straps. Unfortunately, the straps are designed for the regular 20" wide pads and not for the 25" wide pads.

Great bag, but sizing is quite small.

Packs down nicely and good in late spring - early fall, but not ideal in the regular size for a "bigger" person who doesn't sleep on their back. Knowing what I do now, I would have rather have bought a side sleeping bag or a down quilt instead.

Amazing Sleeping bag. Took it up to the Rocky Mountains is AB, kept perfectly warm. I am a side sleeper and didn’t feel the zipper at all which was a nice touch. Also appreciate the small compression sack the bag comes with.

Few nights with it

So far, the nights that i used were pretty good. I like the weight and the the size it compress to. But, the only thing is the compression bag, I feel like the sewing is a bit fragile but we'll see on a long term use.

It’s comfortable and spacious. But what I love most is the straps holding it on to the sleeping pad. It’s a game changer!

Works great, so far. Camping season is not for months, but it feels comfy. Love the toasis feature.
