That sounds pretty slick. When I was younger and cross country skiid with a wineskin regularly I wore it under my sweater only when I needed to, but I see your point. I haven't got a new one yet, but I think it might fit through my neck, as most of my layers are eith zip up or button up. My 200wt fleece top has a pouch. I wear it over my wool sweater, but it should be enough under a wind layer. I've carried bottles there before but never really cold. Didn't carry water last night. Tonight it will be -22C and I will be skiing so we will see. <img src="/forums/images/graemlins/smile.gif" alt="" />
