Once I realised the performance limitations of breathable-waterproof laminates, I stopped complaining about them.
they have proven waterproof to a certain level and they have also proven to temporarily retain perpiration to a certain level.
Ive sweated in my Arcteryx GTX jackets and pants (both raining and non raining conditions) resulting in sweat saturated
underlayers simply because GTX rate of moisture disposal could not keep up with my level of activity. Atmospheric conditions
will also effect how well GTX works.
cyclists have complained about GTX 'leaking' especially at the knee region, but its much more likely that where the knee
typicallly stays in constant contact with the garment during activity is also where one can expect high perpiration build up.
Like wise in armpits- hence why so many GTX jackets have pit-zips to vent excessive perspiration from the region.
Co. like Simms are famous for GTX waterproof fishing waders -
I wonder how they can charge $800 and stay in the market if GTX supposedly doesn't work?
