Designed for children's bodies

JET 12 has a shorter torso, narrower shoulder straps and a smaller hip belt anatomically shaped for children. The padded back panel is breathable, reflective elements on the straps increase safety when crossing the road. The sternum strap is adjustable and has a whistle – useful in case of emergency.

The main compartment has capacity for a sweater, snack, flask and smaller toys. Front zip pocket for small items, two side stretch pockets for flasks, attachment for a headlamp and reflective elements.
