Breathable Clothing I can understand, but how can Waders be Breathable and still breath underwater?
This is a common question and it does take a bit to getting your head around it. All we can say is that it really does work! As you heat up inside the waders, you produce a hot, humid micro-climate inside, relative to the outside. This raises the vapour pressure inside which forces moisture, in the form of perspiration and condensation, through the PU Breathable membrane, leaving you cool and dry. The crazy part is, the colder it is outside, the faster this transfer becomes, so when you are standing in relatively cold water, the moisture transfer will be faster than if you were on the bank in relatively warm air.
