Good thread. I'm mostly interested, because in wet environments, (kayaking) vb don't absorb much & dry fast. I expect my ix uq if wet from condensation would dry in sun and a light breeze in 5-10 min. Down uq probably 1/2-hr +. Not an issue in the AM, but significant at sunset. I also think damp ix would work better than damp down.
I'll know by the end of the summer.
