Weight : 1.53kg; Large 1.6kgVolume : 40+10 LitresBack Length : 46cm | Large 51cm On strenuous hikes in the wilderness or long summer days on walking tours, the AirZone Camino Trek 40:50 is a trekking and hiking backpack that keeps you cool and comfortable, wherever the trail may take you. With a ventilated breathable back, the Camino Trek is ideal for day hikes and lightweight overnight backpacking. With a breathable back to maximise airflow, the Camino Trek 40:50 is hydration compatible, including stretch water bottle side pockets, TipGripper walking pole attachments, ice axe loops, and double side compression for stability. An internal lid pocket keeps valuables safe, while hip belt pockets mean essentials are accessible on the move. The AirZone Camino Trek 40:50 features top entry, zipped front panel, and base entry with zipped divider panel for easy access. An extendable lid increases the volume by an extra 10 litres, large bellows side pockets provide additional capacity, and the versatile SpiderPlate bungee system allows secure external storage. Whether you’re moving fast in the hills, on a long hike, or just out on a hot day, the AirZone Camino Trek 40:50 keeps you cool and comfortable. The AirZone Fixed is our most advanced air-back carry system to date. AirZone technology features tensioned mesh and a large cut out space, reducing weight and allowing air to move freely between the pack and the wearer’s back. The AirZone Fixed has a decreased amount of contact mesh to maximise breathability and air flow. The shoulder harness is turned for increased comfort and the contact mesh is even softer for a comfortable carry. AirZone ventilated packs keep you cool and comfortable whether you’re moving fast in the hills, on a long hike, or just out on a hot summer's day, whatever size pack you're carrying.
