The Proviz REFLECT360 running backpack is unisex and fully adjustable. It is designed to be an evolution of our best-selling Reflect360 Backpack, mainly used by cyclists. Runners, hikers and walkers usually require something smaller that moulds to their body and stays secure when underway so we've worked hard to give a different option but without compromising on the 360 degree reflectivity. We have designed the running version to be able to carry your essentials to where you need to get to, be it a change of clothes, your lunch or a set of waterproofs! The oversized side straps that each have a zipped pocket to house your valuables that you wish to keep within easy access, come around the side of your body to give a secure and snug fit. The ventilated back system helps to allow some breathability and airflow while the fully adjustable chest and waist strap give you great flexibility. Using 100% CE EN 20471 certified reflective material, the Proviz REFLECT360 rucksack's millions of integrated reflective beads helps other road users to identify your position on the road at night. The rucksack is hydration bladder compatible for those who wish to use the rucksack on much longer runs and hikes. About the fabric: The fabric used for the REFLECT360 range is highly technical. During daylight it is a modest grey colour. At night, when the fabric picks up an external light source, eg vehicle headlights, it gives ‘astonishing reflectivity'. The material is CE EN 20471 certified.
