The Stratos range features an AirSpeed back system with tensioned mesh. This back system offers unmatched ventilation and comfort on your hiking tours. The vents in the EVA foam of the spacer-mesh shoulder and hip straps provide additional ventilation. All of the products in the Stratos range have an internal drinking reservoir compartment that makes it easy to stow the reservoir and allows you to get enough fluids, particularly on hot days.
AirSpeed Suspension System
The AirSpeed suspension system consists of a LightWire aluminium alloy frame and a suspended 3D-mesh back panel. Half moon-shaped vents on the sides provide additional ventilation. All contact surfaces are either covered with breathable mesh material or made of perforated, moulded waffle foam. This rucksack sits comfortably and doesn't slip or pinch, whether you're climbing a 4,000-metre mountain, walking alongside the racetrack or taking part in a 24-hour race.
The innovative Stow-on-the-Go fastening system allows you to attach trekking poles to the side of the rucksack. This means that hikers don't have to stop or slow down.
The right size.
To make sure the backpack holds what it’s supposed to, it must fit properly and comfortably. Body weights and heights do not always equate to specific sizes, because people of the same height often have different back lengths, hip widths or shoulder widths. This means you should take your time when choosing your rucksack. To find your torso length, measure from your pelvic ridge (the highest point of your hip bone on the side of your body) up to the lowest cervical vertebra (C7) - the one that protrudes clearly if you lean your head forwards. Back length is decisive when choosing the right backpack size.
