The new JACK WOLFSKIN Aerorise rucksack carry system aims to integrate four key areas of rucksack performance – durability, lightness, ventilation and comfort – into one package. Optimum balance is achieved by placing four independent 3D-printed panels on the shoulders and lumbar areas to provide a lightweight, multi-zone body fit.
The panels’ open cell structures with thousands of individual struts enhance ventilation, maintain comfort and improve load control even with heavier loads. The technology, already in use by the sporting goods industry for high performance running shoes, is provided by polymer solutions provider Oechsler, an additive manufacturer in Germany, and Carbon, a pioneer in 3D printing.
It enables a combination of lattice structure patterns that provide different degrees of vertical and horizontal firmness – soft where comfort is key and firm where more structure is necessary. The design is highly breathable and claims to be capable of reducing back temperatures by up to 5˚C (9˚F).
In line with Jack Wolfskin’s commitment to providing high performing sustainable equipment, there is less waste within the production of the 3D printed designs compared to conventional production. Due to the customisable nature and control over structural attributes of the 3D cushioning, only as much material is used as is ultimately needed. Additional gluing steps or assemblies are not required unlike traditional carry systems.
