The AirZone Trek 45:55 provides a supportive and comfortable carry, however intense the hike. It features our award-winning, fully adjustable AirZone+ ventilated carry system, with patented FormKnit™ technology for all-day comfort. Built from tough, wear-resistant fabric, the AirZone Trek 45:55 features zipped front entry for easy access to the main compartment.
Our AirZone Trek 45:55 hiking backpack is full of trail-friendly features including stretch mesh side pockets for your water bottle; a front mesh stash for your jacket or map; upper and lower compression straps; and walking pole and axe attachments. A large-capacity top pocket provides easy access to essentials, and a flexible lower compartment separates your sleeping kit from your day gear. Along with an integrated rain cover and water bladder compartment, the AirZone Trek 45:55 hiking backpack also features an extendable lid for an additional 10 litres of packing flexibility.
The all-new AirZone+ carry system features our patented FormKnit™ technology to maximise breathability, improve dryness and reduce weight.

Its seamless FormKnit™ technology, integrated hip belt and lumbar pad work together to deliver a supple, highly adjustable custom fit for all-day comfort in hot conditions and challenging terrain.
