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.

Comfy but not warm enough
4 years ago
I took this on a trip where the nighttime low was 32F. Unfortunately the bag wasn't warm enough fully zipped up with hood cinched down. Also, it doesn't pack down as small as other sleeping bags -- it takes up a LOT of space in my 65L pack. I'm really disappointed because the bag is great in many other ways: comfy material, excellent zipper placement options, cinch-down hood. It's fine for warmer weather, but sadly it didn't live up to its temperature rating or packability. I'll be returning it for a warmer bag.

This bag is very narrow for an avg sized female

I was really hoping this bag would be an upgrade from a Big Agnes bag. Its significantly more narrow in the shoulders and the feet and with warm night clothing on, I could barely turn around while inside the bag. Going back to Big Agnes.

Missing hot flashes!
4 years ago
I was cold on 35 to 45 degree nights. This is despite a Therm-a-Rest NeoAir XLite Sleeping Pad - Women's (r value 5.4). I was fully clothed and wore gloves, hat and a nano puff jacket. I think part of the problem was it was too tight and also drafty along the zipper. If I slept flat on my back all night it may have been better. I toss a bit and am a side sleeper. I am tend to get warm easily when sleeping. I am from Florida so I am not used to the cold. A hot flash would have been nice on this trip. The fabric was soft and comfy and the zipperswere great.

plenty of venting options

I actually have the 32f bag, but I thought to pop in here and let people know this series of sleeping bag from sea to summit is top notch! 6 zippers give you the ultimate control over the bags temperature, making it comfortable in hot and cold weather. They are a bit finicky though. The 32f feels pretty dang warm, will test it out in a couple of weeks. The compression sack is good quality, and semi-waterproof. This bag on sale is a steal! A bit heavy, but still a great bag. The 32f is light enough for backpacking-for me at least.

Excellent Sleeping Bag
3 months ago
This sleeping bag has really exceeded my expectations. I've taken it on one car camping and one backpacking trip so far and it's perfect. Kept me very toasty at 28 degrees and I'm usually a cold sleeper (I was wearing wool socks and a mid-weight top and bottom and sleeping on a 4.4 R-value pad). I was also able to easily stuff it back into the compression sack it came in and scrunched it down to a decently small size to fit in the bottom of my backpack. I like all the ventilation zippers--if it kept me that warm at 28 degrees, I'm sure I'll need the vents when the weather is warmer. I also appreciate that it's a little wider than most sleeping bags, I rotate in my sleep and didn't get tangled up at all. It's roomy enough for side sleeping without there being too much extra air to get cold. The one qualm I have it that it doesn't have a pocket, but that's not a huge deal.
