Thule have jumped deep into the hydration backpack game with their new range, and the Rail Pro offers serious impact protection, on-bike stability and good water capacity. While the bag can carry 2.5L of fluid, there is 12L of storage space alongside a removable CE rated back protector. With a tall hip belt the bag is said to be super stable, and thanks to compressible stash panels, even the biggest loads sit close and don't get in the way. The good people at Thule Australia have provided one of these $329 bags for us to give away. Just answer the question in 25 words or less!
