The smaller cousin to the PROVIZ Nightrider rucksack is designed to be the perfect all in one day-sack. Highly visible, reflective, water-resistant and ample storage along with being liquid bladder ready should you wish to add one on those hotter days. The rucksack is also compatible with our unique USB rechargeable TRIVIZ light pack that is attachable/detachable in seconds. Whatever activity you are doing on the roads, simply remove the reflective booster triangle and replace it with the TRIVIZ to ensure you are highly visible above the see of red and white lights on the roads.
