Feeling adventurous this summer? The Luton is a nice companion whether you’re just going out for a run, or going for a nice hike up a mountain. This hydration pack comes with a two-litre bladder with a smartly placed tube for quick and hands-free fluid-replenishment. It has a front zipped pocket with a reflective print and an internal mesh pocket to store valuables and perhaps a Mountain Bar or trail mix. In terms of security and comfort, the bag has a padded back panel system, ventilated shoulder straps, and adjustable sternum straps. A safety whistle is also built into the bag.
