In reply to galpinos:
I think you've hit the nail on the head. I've always either used a waterproof jacket in rain with a pertex windproof for almost everything else except a long detour via buffalo. So Ive been sold on non membrane softshells way before they were called such.
I think if the enduro as a heavy windproof rather than a softshell though I suppose that is what it is. It has survived grit on numerous occasions, has been superbly windproof and breathable for winter walking this year and was spectacular for climbing in Rjukan last week.
Having not ventured as far as Scotland this winter I half wonder whether it would be warm enough (I'm used to a Paramo waterproof which had a snuggly liner)
Membrane softshells look and feel warmer in the shop but I suspect that I'm just being sucked in by marketing.
