The Sport Design Double Bag is a spacious bike bag that can be easily attached to your bike's rack using the Universal Bridge System. It features an elastic bottle strap that keeps your water close and upright, preventing spills. The bag also has reflective accents that enhance your visibility in low light conditions or during night rides. Another advantage of this bag is that it is made from water-repellent material, ensuring your belongings stay dry in case you get caught in an unexpected rain shower. With practical straps, the bag can be easily secured to your rack, and the Universal Bridge System ensures compatibility with various systems, including MIK, Racktime, and i-Rack / Carrymore.
