a couple of months ago there was a similar post regarding the afaw clothing.Back then i was saying they were ok,but now if you check the local dump up here you'll find my smock.Once it leaked that was it.It just would'nt keep anything out.If you are looking at a short term solution,check out the the salt smock,it did'nt cost a fortune,once i have a fleece under it ,its perfect,its quiet warm a no leaks yet 5months later.
As regards the heavier duty stuff i have an old mustad flotation suit for really crap weather fishing mine is 4 years old and no probs apart from the smell


All in all check out the beaches and see what others are using and ask them whats their opinions
Tight lines.
