The Catapult Messenger is an urban-styled sling that holds an iPad or MacBook. The exterior zipper allows for quick TSA-friendly access to laptop and main compartment, and there is a quick-access on-flap zip pocket for your phone or sunglasses. The padded, ambidextrous shoulder strap allows for universal carry as a sling over either shoulder. The custom Timbuk2 Tensionlock feature allows for additional fit adjustments and quick on and off body transitions. There are secondary internal pockets for a power brick or cables, a main compartment for peripherals, essentials and a light jacket. It has a waterproof liner and an external U-lock strap and low profile top grab handle for easy heave-ho.
