Children's hiking backpack with a volume of 12 liters, designed specifically for early school-age children aged approximately 4–7 years. OSPREY JET 12 weighs only around 0.4 kg, has an anatomically shaped back panel for children's bodies and a padded hip belt that relieves the shoulders of the load. Ideal for first hikes with parents, school nature trips or as a first school backpack.

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 details on the straps increase safety when crossing the road. The sternum strap is adjustable and has a whistle – useful in case of emergency.

Organization adapted to children

The main compartment has capacity for a sweater, snack, water bottle and small toys. Front zippered pocket for small items, two side stretch pockets for bottles, a headlamp attachment and reflective details. The backpack is compatible with a hydration bladder up to 1.5 L (separate sleeve), which is enough for longer hikes.
