OSPREY Jet 18L Junior Backpack

Ignite a lifelong passion for adventure with the OSPREY Jet 18L Junior Backpack. Perfectly engineered for young explorers ready to carry their own day-hiking supplies, this pack is more than just a bag—it´s a ticket to building confidence and creating lasting memories on the trail.

Designed with the same legendary performance and comfort as Osprey´s adult packs, the Jet 18L is expertly scaled down for a junior-specific fit. It ensures that your young hiker has a stable, comfortable, and supportive carry system, allowing them to focus on the fun of the journey. The pack’s design prioritizes comfort for smaller frames, making it the ideal companion for everything from family hikes to outdoor educational trips.

The core of its comfort lies in the ventilated AirScape™ backpanel. This innovative system features ridged foam covered in mesh, promoting airflow to keep their back cool and dry, even during active climbs. This ventilation significantly enhances comfort, reducing complaints and extending the duration of your shared adventures. The internal frame provides structure and helps distribute the weight of their gear evenly, preventing fatigue and promoting better posture on the trail.

When your young adventurer is ready to carry their own day-hiking supplies, the Jet 18 features a wide, easy-access opening, a ventilated AirScape™ backpanel and popular exterior stretch mesh pockets for stashing trail snacks, treasures and discarded clothing layers.

Encourage exploration and the confidence that comes from positive outdoor experiences with a colourful, kid-sized pack.
