I always was under the impression that breathable waders were not breathable under water. but after reading a pretty convincing article I guess I was wrong. One blurb states:
"That’s what any breathable fabric does: it acts as a one-way door for water vapor. Even better, it continues to work under water, so long as the exterior liquid is substantially cooler than the body temperature of the wearer. (When the water is 90 degrees, the “high pressure system” created by the angler can’t push the vapor hard enough to counteract the resistance of the “low pressure system” outside.)"
Why am I damp after floating all day on a lake you ask [crazy]
Remember the last time you got in the water with a set of breathable waders on and saw that your fabric had turned dark? It probably felt like you were getting soaked, right? That’s wet out. In reality, you are still dry inside your waders, but because the exterior fabric is saturated and the microporous membrane sandwiched inside the wader cloth doesn’t provide any insulation, you can get condensation on the inside.
The article continues more on wet out and DWR treatments of you like to read the full article follow the link:
