Constructed of 9.25-ounce, 100% cotton ripstop fabric that's engineered to resist ripping and tearing, our ripstop active jac is a rugged choice. Warm, too, it features nylon lining quilted to midweight polyester insulation, plus an attached midweight quilt-lined hood with draw-cord closure. Stow keys, small tools and other items in two inside pockets - the left one features a media port through which you can string a headphone wire to a cell phone or media player. There are two lower-front pockets, including a security pocket on the interior of the left-hand pocket. Rib-knit cuffs and waistband seal in the warmth and triple-stitched main seams add strength.
