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.

No, I do not recommend this product

I bought this bag out of desperation in July when hiking in Banff with a 0c MEC bag and absolutely freezing at 6C . Seemed to work super well until last night it was 3C and I froze to the core using a heavy duty Thermarest -Neoloft r factor 4.7. As well sleeping in wool long underwear and a fleece jacket hat on as well ,wool blanket between me and the thermarest. When I purchased the bag the guy in the shop told me the woman’s bag was actually rated to -12C so that was the game changer .
