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.

Solid bag

Used on Dartmoor in April I was able to assess that yes, it is comfortable down to zero degrees but beyond that don't expect a perfect nights sleep. At -5 I was struggling to get good sleep. So the EN temp rating is accurate. (I'm 47, female) Bag is well made, and not restrictive, rather too much footbox/lower leg space for me (I'm 5'11"). Snugs up well to the face. At 1.2kg it's not too heavy for multiday trips. I look forward to seeing where synthetic tech goes in the near future, it's getting warmer and lighter all the time.

Very warm for a 3

Very warm for a 3 season and reasonably priced. I was happy to get a synthetic that is so warm and at my price point. Spring time in S Devon around 10°c at night it's almost too warm.... and I feel the cold! I'd be confident sleeping in this around 0°
