The Alpinestars Charger Pro backpack is aerodynamically sculpted and semi-rigid for minimal drag whilst motorcycling. In addition, the thermo-formed front panel features a polyurethane-coated pattern embossed polyester for durability with a Jacquard-weave 440g polyester main with a TPE back coating for exceptional durability. It holds approximately 22 litres with expandable detailing allowing an extra 4.5 litres. A clamshell central compartment opening with an inner gusset provides ease of use and a single auto-lock slider zip on the main compartment for secure closure. In addition, the Charger Pro offers a back protector compartment to house the Alpinestars Nucleon KR-CELLi back protector (size M sold separately). An adjustable harness allows riders to adapt it to their torso length for a personalised fit, ensuring stability and comfort and can be used with one hand due to a quick-release magnetic centre buckle for quick and easy use. A removable waist belt allows riders to adapt the bag to their riding requirements. When worn, the belt offers more excellent stability; when removed, it will enable greater freedom of movement. A small pocket at the top of the main compartment allows for easy access to essentials plus a padded laptop pocket is a very welcome addition. A built-in helmet carrier with a colour-keyed anchor point will enable riders to quickly and securely carry a helmet without fear of dropping it. Reflective piping provides adequate nighttime visibility, and a rain cover protects against water ingress.
