Bring the essentials on a gruelling ride: The Outlander 4L XC is a race backpack designed to carry your phone keys, gloves and some extra energy to keep you going on a fast, gruelling ride or race. It's designed for performance-orientated MTB or gravel enthusiasts who value lightweight equipment. The front straps are lightweight and made of highly breathable mesh, while the airy back panel ensures you stay dry and cool during fast, strenuous rides. Hydration during the ride: The backpack comes with a 1.5 litre Hydrapak Elite hydration bladder with a large slide-seal closure that is easy to fill with water and ice. The hydration bladder sits securely thanks to the compression sleeve and the drinking tube can be attached easily and securely with the tube clip.
