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.

Don't love the double zip
3 months ago
[This review was collected as part of a promotion.] Warm bag that packs down well and is light weight. But I don't love the top double zip. My feet would get hot and there was no way to vent because I could only open up the top part of the bag. Other bags with a full zip, I can either open up a vent hole for the feet, or unzip the whole bag and use it more like a blanket. Although I didn't end up using, I like the interior phone/watch/headlamp pocket.
No, I do not recommend this product

[This review was collected as part of a promotion.] I luckily bought the long model even though the normal one is for up to 6'. Very glad I did that. As my first sleeping bag, I got advice from so many people. Some told me to adhere to the temp rating, some said get a lower rating and just sleep on top of it if it's hot. I should have listened to my more experienced friend about sleeping on top. Temps dropped to 40 and I wish I got a bag that was rated even 20 or below. I was wearing just a t-shirt and running pants to sleep and everyone said I ought to just wear more to bed, but I like being less restricted when sleeping. The bag was just enough but would have liked to be a bit warmer. I ended up wearing running pants and a merino base layer to sleep for 50 degrees and it was fine. The material was nice, soft, and light. I appreciated the zips a lot but didn't get to try the split zip at my legs. Highly recommend for the quality!

Nice bag

[This review was collected as part of a promotion.] The only reasons I chose a 4 instead of a 5 are mainly because he hasn't tried it yet. I'm sure it's amazing, but there's always room for improvement. Which leads me to the second point, the colors. We just aren't people who appreciate noisy things. Muted solid colors are our favorite. So this is a little loud for us. But that has zero to do with quality, so overall we're thrilled.
