Stolzy, I appreciate you seem to be on a one man mission to show that Gortex isn't suitable for motorcycle clothing.
Rather than going into the technical ins and outs of how the material works I would be interested to know what you own personal experience of Gortex v other ways of keeping both sweat free and dry is.
I get hot very easily and hate been sweaty/hot in my kit almost as much as I hate being wet. Given that you seem to consider Gortex to be such utter shite I'd be interested to know what you do in order to manage to clock up big miles in shite weather yet remain comfortable, dry and sweat free.
Me? Well I've ridden bikes for a while now. I have grown up with boil in the bag over-suits, army waterproofs, bright yellow deep sea fishermans' kit, various so called waterproof 'named' kit and various competitors breathable membranes such as Shelltex and whilst nothing is perfect (gloves, the subject of this thread, rarely are waterproof to the 'enth' degree) I will not now buy anything other than Gortex kit. That is based on my experience, not what I've read or been told by other people.

PS I should have added that my one piece of Gortex kit has taken me through a Central European and Turkish summer as well as English winters and heavy snow in Central France and the High Atlas. It has suffered day after day of torrential rain and also doubles up as my off road kit (and boy, is breathability important there!). It's now 7 years old and I can honestly say I have never got wet (or sweaty) in it......................
