My snowbee wading jacket has seen better days and I will be heading to Sutherland later in the summer ....where it can really rain and we will be in an open boat. My fishing buddy has a Simms G4 Jacket which he says keeps him dry even in a Suthrland "all day pish". My budget wont stretch that far and at least one good boat angler said, forget fishing brands and get a mountaineering type jacket as they are better. Any recommendations / thoughts? The snowbee was good but over a whole day , didn't manage to keep completely dry.
