Performance sells this craft jacket which makes at least an effort toward pit and back venting. I have been wearing one since fall, it is a good winter jacket for my neighborhood, wear it in the 40sF over a t-shirt, 30s w/ long-sleeve shirt, 20s w/ 2 shirts. The venting isn't nearly as good as my burley jacket, but it is vented better than any comparably GLOWING jacket that I've been able to find. The lack of pockets is grating from time to time. But again, it's easy to see.
