The Cat® 17 inch Tool Backpack features 47 pockets for ample tool and gear storage. It's built using heavy-duty 1200D polyester weave for maximum strength, durability and moisture resistance. A high-visibility inside floor helps you locate tools and parts quickly while the reinforced bag bottom resists moisture, sagging, tearing and abrasions. You’ll carry your loaded backpack safely and comfortably, thanks to thick back panel pads and padded adjustable shoulder straps. All pads are finished in breathable mesh fabric for increased ventilation.
