I am looking at the Katabatic Flex online, and I notice that there is a snap in addition to the drawcord at the footbox to seal it. They have a 3 photo description showing how this works, but while I think I see reinforcement for the snaps in the pictures, they don’t really show how the snap works.
Does anyone have one of these that could post some pictures? Does it reliably close the hole in your experience?
Thanks for the help!
