I have had a no peep on for several years and although I have had to wipe it off on a few occasions in real dumping rain, it usually does not present much of a problem. I can see how freezing weather could cause a problem. I also live in western Washington and I am familiar with RAIN, but I love the no peep and will never go back. Sort of interested in the new version of no peep, but got everything on my bow shooting so sweet that I don' t want to touch anything.
