I have an ongoing joke with my wife that GoreTex is a myth. We both spend a lot of time on trail and once I splurged for GoreTex trail runners. The first time I wore them on snow I was amazed. My socks stayed dry. Three outings later they were no different than non-GoreTex trail runners. Anecdotal evidence but there seems to be a huge spectrum of GoreTex effectiveness across garments. I'm not sure how these items are manufactured. Is it possible some items have "more" Goretex or have it applied in a specific way to make them last longer than others?
