Winchill can cut a hunt short if the hunter is not wearing the right hunting clothes and body heat is blown away.  Insulate your core body and stop cold winds and winds chill with the Drake MST Windproof Layering Vest and continue to hunt as the mercury drops out of sight.  This Drake vest has a standup collar and handwarmer pockets for additional warmth.  The water resistant exterior helps keep your drier and still warmer.  And, with a remarkable ratio of warmth-to-weight, this hunting vest is less bulky and thus layers more efficiently and comfortably under a Drake Jacket.  Less bulk means much better range of motion for shouldering and swing a shotgun.
