The Roto Grip MVP Backpack was designed specifically for BOWLING and BOWLERS. It all started with the spacious Ventilated Shoe Compartment that caters to bowlers who use shoes with interchangeable soles and heels. The mesh pockets keep shoes in place, while the zipper pockets keep soles and heels separate, and vents at the bottom let shoes air out when not in use. The main compartment was created with the intention of holding a laptop and the Roto Grip MVP Accessory Case comfortably. There's still plenty of room for a light jacket, shirt, or even a purse, making this backpack versatile for various uses. The backpack is made of 600-denier Polyvinyl Fabric and features multiple pockets, dual-side elastic mesh drink pockets, adjustable padded shoulder straps, and an easy-carry top handle. The Shoe Compartment measures W: 12" x D: 4" x H: 18", the Main Compartment measures W: 14" x D: 7" x H: 20", and the base dimension is W: 14" x D: 11" when sitting.
