Constructed of our industrial weight Rugged Twill, this bag is built to carry a lot of weight. It's loaded with handy day-in, day-out features including full width open pockets on each side and end pockets for small items you need to grab quickly. Inside are four roomy full-length sections (even one for large laptops), tall enough to hold a standard writing pad vertically. The easy-access zippered front compartment has plenty of slots and pockets for cell phone, pens, laptop accessories and tools. Adjustable and removable leather shoulder strap with brass-plated roller buckle and leather pad. Leather grip and storm flap with snap closures. Double bottom. Meets carry-on requirements. Made in USA.
