Skurka is of course correct that it’s easy to overwhelm the Gore-Tex membrane when you are working hard and perspiring. But this is not exactly breaking news… there’s a reason pit zips and soft shells were invented. Making a big point of this, sort of feels like shooting fish in a barrel. Unfortunately if you read his other writing about Gore-Tex (and waterproof breathable membranes in general), it is clear he does not understand how the technology actually works. He refers constantly to ambient humidity, which is irrelevant, and even gets some facts about humidity wrong.
