Lighter in weight yet strong, our Down Kalkaska Active Jacket helps you pull your weight throughout a long work day. The outer shell is 4.25-ounce, nylon canvas with a durable water-repellent finish. 100% Nylon down-proof lining with quilted 550 fill down insulation provides warmth. Carry a lot of items? The Kalkaska Jacket is well outfitted for all your storage needs. It boasts two large lower-front pockets with snap closures and an interior chest pocket with a media port to let you string a headphone wire to a cell phone or media player. Rib knit cuffs and waistband help seal in the warmth, and triple stitched main seams add strength.
