I've used breathables for the last 5 years. In summary such items are in breach of the trade descriptions act. All are utterly useless and in an honest world they would have to be re-branded "thoroughly leakable waders".
More details:
I fish a fair bit for trout. "breathables" are lightweight and right for the job according to the "tin".
Friends have expensive Simms ones. They leak, "but it isn't that bad and you hardly notice after a while". I buy Vision. After a week I'm pleased. Then I kneel down and they leak. I repair them. This is a lenghty process. You turn them inside out fill them with a hose, mark the hole. dry them out and repair them. Off to the river ..... yup..... they leak. Hang on these are "Vision Extreme" and supposed to be good. Return direct to Vision. I asked my dealer. They had so many returns they said It might be better to return them myself... cheeky.
Vision offer me a pair of "Flywater" at half price. Why not, i'll have some of that.These will be better. After a week i'm pleased. Then I kneel down and they leak.................
I despair. Phone the lads, Scierra, Ron Thompson, Simms (again). What should I buy?
Apart from one guy (a £1aire) who said ORVIS, the rest said thin 3mm neoprene or OCEAN old fashioneds - they never leak!!!
Breathables will be even worse in salt water as most are not Deet approved.
From my experience they are a complete waste of money.
