The Silver Edition is particularly narrow and light-weight and is comfortable to wear thanks to the neoprene hip strap. As such, it is extremely well suited for freeriders and offpiste skiers. Additional protection is provided by the certified Komperdell soft back protector which can effortlessly be attached by a hook and loop fastener instead of the standard back pad. The activation handle is height-adjustable and can also be optimally adapted to left-handed users. Combining the Silver Edition with Vario Zip-ons up to 32L packing volume is recommended for optimum fit and comfort because of the neoprene hip strap; it is compatible with all Vario packs. Every Silver Base Unit is delivered with a cover and an 18L Zip-on with Carbon Cartridge. "
