There's windproof, then there's super sealed windproof; How much ventilation does everyone else like?
I have a great Nike winter training jacket (old old!)with pit zips- which doesn't fit right now, but I liked the variable venting. I've seen mesh linings with slit backs, grommets in the pits, or is Gore tex the stuff?
My current jacket is such a hothouse I turn into a big sloshing bag of sweat, and I'm going to remodel it with vents- just need to decide how. Eyelet/ grommet hole things are easiest to put in, but I'd need to place them right... So the wind doesn't roar in!

Suggestions?
