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 Loft for the weight

Took this for several overnights in WMNF over the summer. Temps got down to approx 40degF and this bag was way overkill. I'm a cold sleeper and left it unzipped all night. Leaving the gills open meant I did not sweat either. Looking forward to trying it out in colder temps. Packs down to incredibly small volume (~1L) and lofts back within 10 mins. Very comfortable and cozy for 6' tall

Not 15 degrees!

I have been backcountry camping, mountaineering, and hiking for over 55 years in numerous countries and varied climates. My worn out 15 degree Marmot Hydrogen has served me well for the past 15 years and was replaced by a gift Kayu 15 degree bag. I have used it eight nights and have been cold in 30-40+ degree temperatures. I have had to sleep with a vest, thermal wear and to the extent my puffy jacket in a recent Cascades trip. The loft is shallow and the bag feels porous to incoming cold air through the baffles. I will try and return the bag to the retailer and purchase or exchange for a better product. I've heard good reviews about Nemo products but cannot recommend this bag.

Expensive and not warm
3 years ago
I have given this bag multiple chances for me to like it but in the end it’s not warm at all. I have been freezing in 40-50 degree weather and have had to sleep in a hat, base layer, and jacket when I was in Colorado and it got mid 30s. I’m not sure if I got a lemon that doesn’t have enough fill or what but I’d buy a different bag and save yourself some money.
