Breathable??
Well, the Sundridge suits claim to be breathable, indeed my combo was made from their material called Silkatex - yes, it does breath, but not like 'gortex'.
Basically, the material used for floatation suits that is 'breathable' just means that it is nylon which has small holes in it!
When I jumped in the pool, the material as well as breathing and letting air in and out, it also let water in! It isnt proper breathable material.
As far as im aware no one makes a fishing suit that has inbuilt boyancy and is made from a decent goretex material - cost I think is the main factor. The Imax suit doesnt claim to breath, but the nylon is a decent heavy duty waterproof quality.
I have a couple of Musto jackets, 1 inshore and 1 offshore and a pair of matching salopettes - these are the nuts! I use them most of the year now, except in the winter when I need warmth. I agree, these are made from HPX material and are streets ahead of what you can buy for fishing. So yes - worth the extra money - but you tend to cringe slightly when you spill mackerel guts down the front of your expensive sailing jacket!
