According to eVent, their fabrics “lets sweat escape up to twice as fast as common waterproof/breathables.“. Now that’s a big claim but is it true? It seems to me that GoreTex “breathes” at the same rate judging from the video below. The only way to know for sure if this claim is true is by using a high-speed camera and timing it.

It may be just a slight difference but who knows how it performs in real life situations. That slight difference can be significant, or not. I have to say that it’s more of a magic show than real proof.
