Lululemon gray jacket with unique back zipper.

Lululemon En Route gray/black jacket with unique back zipper for venting/cooling body after workout. Flowing black fabric shows when back of jacket is unzipped. Zip up high collar. Soft cotton fleece. Ribbed stretchy material on sleeve. Zip side slant pockets outlined in black. Slim fit. Hip length. I cannot find the size tag so please see measurements. I think it is a 6 based in how it fits me (again, slim fitting).
