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.

Unhappy with purchase
No, I do not recommend this product
I wish I hadn't bought it. I used it for cold weather backpacking on the PCT. The zipper snags all the time, and I can't get the zipper to go all the way up so I am unable to take full advantage of the draft collars. I do not feel it is even close to a zero degree bag. Maybe if the zipper didn't snag so badly it might feel warmer, but I can feel the cold seeping through it. The footbox felt warm, but above that, even with all my clothing on I have been feeling chilled in mid 20s temperatures. So, unfortunately, I will have to replace it with something warmer and with a better zipper. Yes, I am disappointed. I do not recommend it.

warm bag, bad zipper
No, I do not recommend this product
Ive used this bag for 2 months consecutively, the coldest ive used it in is about 15 degrees, its always been very warm. The shell repels water well, i haven’t had any condensation or rain get thru the bag. As other reviews mention the zipper snags a lot, for the price of this bag the wuality of the zipper is pretty ridiculous. if you arent careful with it, it will pull off the tracks completely. I have had to replace the zipper pull twice because of this. There also isnt a velcro piece at the top of the zipper so if you move a lot in your sleep it might start to unzip on you. It broke in the middle of a 2 week trip for me. On long trips i recommend bringing a zipper repair kit, it adds almost no weight and will get used. When i first used the bag the loft was great and it even added a lot of comfort to my sleeping pad, but after about a month of use, all the down where i lay is very flattened. I dont know if this is the down not being distributed evenly or getting compressed overtime (Even with storing it unpacked and fluffing it before using it) Depending on your sleeping pad this might affect your warmth.

Great Bag, Not-so-great Zipper
Yes , I recommend this product
I use it for backpacking with the scouts, its wonderfully light weight. I am small guy so its roomy enough. You have to really take your time with the zipper as it snags the second you look at it. But for the zipper it would be a five star bag.

Yes , I recommend this product
I bought this last year, for a few tracks to Nepal, base camps were all above 19,000'. Great bag, zipper is horrible, had to replace the zipper after first trip, otherwise it's very warm.
