I asked a similar question about "Rivers West" gear awhile ago (check one page back). In the meantime a friend of mine has used a pair of the Guide pants for protection while hauling a few crab pots out of deep water (300+feet) and he was pretty enthusiastic about how dry he was after a very wet and cold job!
I'm buying at least a parka made of H2P for our normally sloppy and cold Fall and Winter deer hunting season. If I like it - I'm getting a pair of matching pants!
