Pat I hunted all this season in NW Montana (generally wet for the west, think of it as Seattle Lite) with no problem. But that is one reason I wax them. Several long days in drizzle they held up fine. As far as perspiration, I walk and climb around a lot again had no problem. They seem to absorb quite a bit of moisture without any obvious negative effects. I've never had one loosen up. Feels better than leather to me because it's more solid. Some folks might not like this. Only potential problem might be they are loud, but strike plate of other material can take care of that. Dave
