You do realize that EVERY waterproof material is able to held under a tap and not have water get thru dont you? Every waterproof material is also 100% windproof. I can put on a garbage bag and hold it under the tap also, same result.

A real test is doing an aerobic activity, such as cycling at a fast pace, in temperatures where you still sweat, and see how wet your base layer is after an hour or six. The plastic bag works well at temps near freezing since you hardly sweat at that temp, but at 60-65 degrees, wearing either goretex or a plastic bag, and cycling hard, most everyone will be soaked in sweat.

Goretex also relies on a difference of humidity on opposing sides of the fabric in order for the vapor transport (breathability) of the fabric to work. Which is why it breathes great when you wear it on days its not raining, but as soon as its raining on the outside, and your sweating on the inside, its vapor transport ends.

Heres a chart. I'll pick quite a few materials above goretex

Heres another page with a good description of Goretex's history, its about 1/3 the way down the page

So i'm glad your happy with your purchase, but no i dont share your love of goretex. I choose a few other materials as much much better, they just dont have gore's billion dollars of marketing behind them

Ok... relying on a difference in water saturation levels is a requirement for any water wicking. This is just physics and chemistry. Also, goretex wasnt really designed to be worn in 65 degree weather at least not the products I have. The beauty of gore-tex is that it doesnt have to have a coating to be waterproof and windproof. The 9billion pores per inch do it on their own. Most gore fabrics are layered, and have a coating on the outside fr improved performance though. Lastly, gore products dont lose their performance after being worn or washed.

There are a ton of waterproof products around... a plastic bag being one of them... but a plastic bag definitely does not have the same properties of goretex.
