DAKINE Shuttle 6L Hydration Backpack - Women's Daytripping, One Size

When we're on our bike, we don't need a full pack weighing us down, so we love the minimalist style of the Shuttle 6L Backpack. This backpack comes with its own 2-liter hydration reservoir that fits snugly in the main compartment. The rest of the space is perfect for necessities like a pump and tools or a spare set of sunglasses.
