The Travel Backpack from Peak Design is a bag that can serve as the core of a versatile transportation system for photographers, multimedia creators, and dedicated travelers. Expansion zippers along its spacious main compartment allows this backpack to increase from 30L to 45L in volume, while inside, a zippered partition system forms an optional front and rear divider. To further enhance the ability to organize this bag's contents, separately available Peak Design compartments that are specifically designed to store camera, video, audio, and digital media equipment, as well as apparel or small electronics can be arranged within the Travel Backpack to create a customized carrying solution that can be changed as needed.
