As the makers of the Original Swiss Army Knife, we pride ourselves on delivering high-quality, functional solutions that allow you to enjoy life’s adventures. That’s why we created the Etherius Collection. Constructed of 100% pure polycarbonate, Etherius cases are both ultra-strong and ultra-light. Furthermore, with a zippered expansion system, Y-shaped compression straps and two zippered divider walls, they contain the packing ease you expect from Victorinox. So where does the name Etherius come from? The base of the word, Ether, means the clear upper regions of the sky beyond the clouds. The suffix –ius indicates “made of” or “belonging to”. Try it. Pick it up. Give it a spin. We think you’ll find it all makes perfect sense.
