In reply to AlanLittle:
I'd love it if my windproof cycling gilet had a waist drawcord instead of sewn elastic - would work much better when I'm mucking about running in it and not ride up.
Can't actually think of any of my outdoors jackets that don't have a waist drawcord - only some very thin fleeces that you'd only usually wear casually or under something with a drawcord (although I'll admit to putting a drawcord into one of them to stop it getting caught on karabiners on my harness).
The windstopper gilet I'm currently wearing doesn't have a drawcord, but is a pretty close fit anyway and really doesn't need one.
