- Per industry standards, the Limit rating is considered the benchmark for men, while the Comfort rating is considered most applicable to women
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.

Excellent choice for a 3-season bag (25°F version)
Really solid sleeping bag for 3-season weather and I highly recommend it. I am very satisfied with it for both backpacking and car camping -- the condensed size means that it even fits in my one allotted "Personal Item" backpack when I fly. I've slept into the mid-30s in it without much issue of getting cold. When it's that cold, I'll keep my puffy jacket in it both to keep the jacket warm but also add a little more insulation. The vents are a nice touch, especially in the toebox. I've used it in both high humidity climates and in the desert -- always breaths well and doesn't get clammy or damp on the inside. I have a short bag because it's the same as the women's sleeping bags (I didn't like the colors of the women's bags).
Love the Coda!
Nemo donated a few Coda sleeping bags to our queer outdoor gear library, and we Loooove this sleeping bag! We're really into the fact that it's not gendered (gendering sleeping bags sure is silly) and love how lightweight the bag is. It's also super cozy. The only issue we have is that the footbox doesn't fully unzip, but it's definitely not a dealbreaker. Highly recommend this product and the others in the Coda line!
