Designed to be versatile and durable, the Think Tank Essentials Convertible Rolling Backpack will safely hold a large range of gear and keep your kit safe whilst travelling. The bag is made from high-quality materials which coat the exterior, protecting from drops and falls e.g. the Hypalon reinforced rear panel. Aside from this, the bag offers smooth and quiet rolling thanks to its custom-designed, 80mm wheels which have sealed ABEC grade 5 bearings, and for when the terrain gets too rough you can deploy the shoulder backpack straps which allow you to carry your gear on your back. Think Tank has also sized the bag to meet most airline carry on requirements.
