Imported.
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.

Game Changer!
Everything I loved about the ultralight sleeping bag, but without all the things I disliked! The zipper is now a little bit more to the front without being entirely up front. This makes it much less awkward to close up at night and deal with the zipper all together. It is still mummy shape which keep me warm at night during colder canadian nights. The headwall seems to also have changed and it wraps my head so much better than before. It feels well protected and warm, even without a proper pillow. Also, can we talk about the fact that the bottom can open up?! I can now walk around camp fully wrapped up, and THAT is the true game changer! You would think adding a zipper down there would make the bag so much heavier, but it still packs quite small! Absolutely LOVE it!
Great Year Round Bag
After using Ultralight quilts over the past few years, I love how warm this bag is. There are tons of great features like the zippered foot box and vents which make it suitable for summer use, but the traditional bag design make it very warm to use in the winter as well. I put several hundred miles and many nights of use on this bag in Alaska, Colorado, Arizona, and New Mexico and it's still going strong! Even with my dogs getting it dirty, it doesn't show any signs of breaking down. I also like that it balances weight and performance. This is a solid choice for a versatile, ultralight sleeping bag.
Great sleeping bag with tons of clever features!
Just got this bag and I'm stoked to be upgrading. the thermal gills work very well, and the full collar is great for keeping drafts of your neck. can't describe how much I love the zip at the bottom. The only complaint I have is that the advertised compressed volume differs from reality. I got the Long length and the spec sheet says it should compress to 6L. I was barely able to get it into a 10L stuff sack. Maybe you can get it to 6 with an industrial vacuum chamber, but no chance in the field. Love everything else though!
Great bag
Light and warm. I am 6'6" and 240lbs, so I have the long bag. I have room in the shoulder and hip area to move and this bag allows me to move inside it without twisting it up, it is awesome so far.
Versatile and cozy
I have been using this sleeping bag for quite a while now and really like it. It's lightweight and has a handful of features that make it versatile and my go-to sleeping bag for chilly conditions. First of all, it is lightweight and compresses down nicely for its temperature rating. Second, the venting it has is absolutely killer. It is super effective, making it possible to bring this bag for a wide range of trips with varied low temps. I have taken this bag on adventures where the lows were 10°f, pretty much its limit, and as long as you have the proper sleeping pad, the Coda 10/20 will keep you warm. Last thing I'll mention is the waterproofing on the footbox. It's great! I never wake up to wet or cold feet. Of course I do what I can to minimize condensation in my tent, but some condensation cannot be helped when the temps fall. And when that's the case, I am grateful for the design of this bag! I trust it to perform well.
Slept like a baby.
Did our county search and rescue training in western Washington in January with it. It was just above freezing and rainy, like it usually is during the winters here. Worked like a charm. It’s going back out in Feb and March for more of the same. Used it with the Tensor Extreme Sleep pad. I went to bed wet and woke up dry.
Incredible bag, thoughtful features
If you want to a top notch bag this delivers. For a mummy bag, the long fits me really well at 6’3 with enough shoulder width to be surprisingly comfortable. Excellent build quality. Love the waterproof head and foot box and the thermal gill in no joke when it’s warm. Can’t say enough good things
Happy wife, happy life right.
Got this for my wife for our Alaska hunt later this year. She’s one of those 5 blankets on the bed and the ac is set to 75 kind of people. We tested this sleeping bag out in the back yard on a cold night was roughly in the 30s and she said she slept great. Should be good to go.
Very Warm and Comfortable
Camped in 30-degree weather and this sleeping back kept me nice and warm. Loved the ability to vent the upper section and open the footbed to increase airflow to your feet. Highly recommend.
Great sleeping bag
I just used this sleeping bag for the first time and it’s the best one I’ve ever had. It does great with colder temperatures. I would recommend to anyone looking for a new sleeping bag.
