The Moki bike pack makes it a breeze for little rippers to stay hydrated on the go with an included Hydraulics LT 1.5L reservoir. Designed with the same features as our adult packs. the Moki offers a low-profile design and ventilated airmesh harness which provide a comfortable carry in a riding position. A front shove-it pocket and external zippered pocket keep small items organized while a blinker light attachment loop helps keep kids seen.
