This baby has it all. 12.5 ounce 100-percent Cotton Canvas shell, 280g, 100-percent Polyester double-sided Fleece lining, exterior and interior zippered pockets for stowing your gear, side seam zippers for cinching the waist in, streamlined shoulders and a low-cut collar. It'll help take the edge off cooler weather, but won't get in the way of getting the job done.
