Had one of these[/url] for about four years now – Gore Oxygen. I really like it, very lightly insulated, close but not race-tight fit, completely windproof, very water resistant. Gets used pretty much every ride from late autumn through to early spring.
I’d never use Gore Windstopper Soft Shell stuff on the mtb, but it really seems to suit the steadier output levels you get on the road.
I like the way that Gore has different cut jackets so you can pretty much pick and choose anywhere on the spectrum between mtb baggy through to race-snake close, but pretty much everything else I use on the road is now Mavic.
