Carrying everything you need for mountain days, the Aeon is designed to give you freedom of movement over all terrain. The close-fitting Air Contour X carry system is sturdy enough to carry heavy loads, whilst keeping the weight centred for agility on steep, tricky trails. Its semi-rigid structure and vacuum formed back panel, moulds to your shape and keeps the air flowing. It has a wrap-around stretch yoke that fits neatly over the back of the shoulders for a soft, secure fit, with an adjustable back length and forward pull hip belt to personalise the fit for all day comfort.
