I think Peter Storm is of a quality that you would only use them for casual wear and not garments intened to take on seroius trips. If it is one found in a boat shop specifically designed for yachting, then it would be okay, but the more fashionable type items found in town shops may not be up to the same standard, a bit like the way Berghaus has gone. I used to have an over the head Peter Storm waterproof. It was strong but as it wasn't gore-tex, it made you sweat.
If you get a Peter Storm gore-tex, then it will work but you could probably get better for the money, or by adding a little extra.
