Is using 2 layers of gore-tex developed fabrics really that much of a technological leap?
I've never handled veilance but I can't really see what's so great about their fabric. It seems to me like it's the same as any other gore jacket.
The construction and machining that goes into it might be excellent. Still I have to think that all these innovations (microseams etc) do is very slightly reduce the weight of the jacket. Might be useful at the top end perhaps.
e.g. waterproof zips are unnecessary if you just add a placket to the design.
Those details are nice to have though and I guess contribute to the nature of the garment from a stylistic sense.
I wish there was more actual fabric innovation as it seems that everyone is still stuck with gore-tex.
From a technical standpoint, these features do make a difference. From a design point, not so much, but when you're using these things for what they were designed for little things likes water proof zippers make a sure difference. I guess it all depends on how you view "technical outerwear"
