The adjustable AirZone Centro system allows for better ventilation, with the tensioned mesh and cut-out space giving greater breathability across your back area.

It uses their AdaptiveFit hipbelt and harness for extra stability and support when carrying heavier loads, which leads to a much more comfortable carry overall.

The floating lid allows you to expand the capacity from 33-40 litres which, along with the Spider Plate bungee system, afford you various extra storage options.

Their unique walking pole holders have a TPU cross grip for poles with spikes and a pull out elasticated loop for poles with rubber cap/bungs, so whichever style you prefer you've got the option to secure them safely.

An internal pocket holds a hydration bladder with exit points for the hose so you can drink on the go, but if you prefer to carry a bottle or two then there are large stretch mesh pockets on either side of the pack.
