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.

Received as a present from my wife. I did not have the heart to tell her about my displeasure with the condition I received it in.
No, I do not recommend this product

Gore-Tex is a game changer
2 years ago
I took this on a recent fall backpacking trip in the snowy Idaho mountains and was SO comfortable. The gore-Tex shell allowed me to not stress about it touching the inside of the tent walls and getting wet, or getting wet from the snow blowing in or wet dogs snuggling up with me. And it’s the warmest sleeping bag I’ve owned. I was cozy in it down to about 15F. Anything below that, I’d prob go for a sub-zero rating. Also I’m about 5’9 and almost maxed out the length for this bag.

Good warm material and insulation dose the job of breaking wind and staying warm tested in below 6 degrees F.

Lives up to the rating!

It says 0 degree limit and 13 degrees comfort on the bag itself. I used this bag in conjunction with a 4.4 R-value sleeping pad and Gore-Tex bivy sack for a week. It was -2 the first night with 3 inches of snow on the ground, and this bag was still comfortable (I wore appropriate base layers as well). Other nights varied between 5 and 20 degrees, and this bag performed superbly. It is durable and packs easily. Highly recommend.

Nice and toasty.

I am replacing a 15 year old zero degree down bag and I am very impressed with the quality of this bag. I am 6’1” so I purchased the long bag. The outer material is very water repellent. There is ample insulation to keep everything nice and toasty. I have yet to use it out in the cold but I’m sure it’ll do great. The color in the picture doesn’t look as bad in person.

Amazing idea of a bag!

All these years sleeping bags have been approached by treating the feathers to be water resistant. How common sense and awesome is it to just have a vortex shell instead. I hope this becomes standard in cold weather bags, to have a gortex shell. Awesome!

Good bag, not for large people.

Lightweight and water resistant. 5’8” skinny build fits good. Would not recommend for larger frame individuals. Worst part is does not have a draft tube under the neck so on a windy night the bag was a little chilly.
