I wore it for two wet mornings and a windy wet evening and I stayed bone dry even when crawling through wet rushes and sitting on stand in light drizzle. Its 100% silent and very comfortable to wear. As both pants and coat are breathable I never got damp underneath. The pants are a little on the light side so for colder months I would wear a thermal base layer underneath but still no issues with them .
GRAFF have a made a really good suit here and any stalker or general hunter will not be disappointed.
