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.

Super impressed
1 year ago
Super impressed! I was sitting with this in my cart for months finally my friend got one and was impressed with the feel of the material. I love how small it packs up. The weight is on point for a 0°f backpacking bag. Im 5'7" 190lbs and when inside the bag with just mypants and shirt not alot of room to move which is what you want but.... if your a little uncofratble not being able to move you might need to go with a bigger size. also if you wanted to add liners you might like the extra space. We live in Kodiak,AK always blowing and raining and this bag is what you want.

Buy this bag… period. The concept of treating the feathers verses just giving the bag itself a gortex shell feels crazy this hasn’t been the move all along. Not worried about winter expeditions anymore.

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.

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.

Great bag for cold nights
1 year ago
This bag is great! I took this up to 10,000 ft in CO for an early Nov backpacking / hunting trip and it was perfect. This bag packs down small, is super warm, and the Gore-Tex shell kept the frost from getting the bag wet. The only downside is that it's a little loud when moving around (a weird qualm, I know) but that's a small price to pay for the Gore-Tex shell keeping everything dry.

Amazing idea of a bag!
1 year ago
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.
1 year ago
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.
