Rons are a bit of a liability when they're really thoroughly soaked, but anything less than that and IME they're fine. In dreich and drizzle they tend to dry out about the same speed they get wet. And they're cheap and easy to find to try on.
They re-did them a year or two ago, haven't tried the New! Improved! ones so don't know to the extent they're, errr, new or improved...
