Our 4 Kifaru Slick bags ..... But the 0 degree rating is a tad off as I begin to feel chilled once the temp drops into the mid to high teens and it weighs just shy of 3 pounds.
I was waiting for KUIU to come out with their Superdown bag but it still hasn't seen the light of day yet.
Interesting info on the 0 Slick, same as many others have posted. That means it weighs the same as NF Cat's Meow, and has the same warmth, except NF doesn't call theirs a 0 bag.
Feathered Friends is currently testing some version of "dry down".
Jacks R' Better's quilts can be ordered right now with Active-Dry down.
