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.

I have ridden over 1k miles since my last review.

This includes Montana in October, cold wet days in Oregon and Washington. it has lived up to what I said I thought it would. I am surprised you would call me out. Maybe the "other" review should try actually using it. The bag is fantastic and I have yet to be cold. Maybe you need to invest in some smart wool...

Bought this for bikepacking trips.

After suffering with light weight cheapie sleeping bags for the last two years on two trips from North Bend to Spokane and then Spokane to Glacier National Park I came to the realization that i needed to spend some money to get a proper sleeping bag. In Idaho I literally froze since summer came late and got really sick which was a massive downer for a bike ride. I barely slept because I was so cold and I swore after that I was not going cheap again. I first had upgraded to a nemo insulated pad (already have a hornet 2p tent) and saw this on discount during a nemo sale. I just got it and tested it out in house and its really nice and it packed up quite compactly. It comes with a nice stuff sack that helps. The color is nice and it will fit nicely in a handlebar bag or pannier. Once I get this out in the weather Ill follow up with this review and how it worked out on the trail with finite space constraints.

Buy a Garbage Bag Instead

The previous reviewer might want to use the bag first before writing a review. And if they were looking to “spend some money to get a proper sleeping bag,” they will be sorely disappointed with the Kayu. I bought this bag for the same reason: it’s super lightweight and compressible and can fit well in a handlebar bag. But it’s all pointless if the bag can’t keep you warm in temps anywhere near the comfort rating. I’m writing this review from Tucson (Tucson!) where I’ve spent a second miserable night in this bag and the low was 54 last night. When hunkering down in my bag to stay warm I could see all the voids in the down tubes causing countless cold spots. This bag is a joke and will be returned.
