The Airport Security V3.0 has TSA-approved zipper locks for the main compartment, and a high-strength coated cable and combination lock for the laptop and for securing the case to an immovable object. Store your water bottle and tripod in the convenient side pockets. Additional tripod straps are included. A retractable trolley handle, in conjunction with two 80mm, ABEC, grade 5 ball bearing wheels, makes travel over flat ground easy. Grab handles on three sides are for lifting the Airport Advantage in and out of vehicles and overhead bins. An included rain cover with storage pouch helps protect the case from dirt and inclement weather. Quality materials such as water-repellent 1680D ballistic nylon, closed-cell foam padding, tall skid plates, and reinforced PE board dividers offer strength and durability. Photographers will appreciate the handsome business card holder located on top.
