Smokepole, weight has been a serious consideration, but the wool jacket I've been looking at at the local sporting goods seems to me thick enough without being very heavy. Do you think I would regret the weight of just one wool garment? But, regardless of weight, you've drawn my attention to another problem it may have, it only buttons half way down. Do you think I should aviod a garment if I can't get it open all the way for ventilation?
