With a padded inside compartment for your laptop/tablet and a total volume of 23 liters, the Velocity High Visibility is spacious enough to carry everything youll need at work, school or play. And what makes this daypack really special is the reflective yarn woven into the polyurethane-coated fabric. The yarn, which is evenly distributed across the whole daypack, is highly reflective as soon as its struck by a motorists headlights, thereby significantly increasing the likelihood that youll be detected at night in street traffic. Even during the day, the fluorescent yellow is a colorful eye-catcher. The practical Velcro roll closure and the ergonomic carriage system make this daypack a favourite accessory for every day. You can also attach an additional rear light or helmet to the mount on the closure.Specification: Fabric: PS50X/PS50CX Height: 50cm Width: 30cm Depth: 16cm Volume: 23L Weight: 750g
