Hi all, I'm a new convert to VFF's, having just bought some KSO's about a month ago. My husband has had his Flows since February. We're both loving running in them, but I'm wondering about temperature changes if we're both going to end up needing Flow's and KSO's. Not that I'm that likely to run in really cold weather anyways, but who knows, maybe I really will be that dedicated come winter!
What are your experience of VFF's in the varying seasons?
