The updated ZAP TOP bag is now slightly larger and available in four colors: black, gray, chestnut brown, and light gray. It features the AVS system, an 11-liter main compartment, and expandable side pockets for an additional 8 liters of storage. A bungee cord secures items such as bottles or a sweater. Inside, there is a zippered mesh pocket on the lid for storing smaller items, and the detachable shoulder strap along with the carrying handles make transport easier. To prevent theft, this product is equipped with the AVS PREMIUM ADAPTOR with a plastic key.
