When we are mountain biking, there are specific essentials that we never ride without. The Osprey Salida 8L Backpack is our number one choice when searching for a mountain biking-specific backpack due to its small and compact design, neat organizational features, and ergonomic and comfort features. All of our essentials fit into the zippered compartment that features internal organizational pockets, and the Salida allows us to attach our helmet to the back of the pack when we are not riding. This bag has a 2. 5-liter hydration bladder that fits into its separate zippered compartment and features a magnetic bite valve attachment. With its small size, Airscape suspension and backpanel, and its comfortable harness and hip belt, the Salida is super comfortable to carry when riding, evenly distributes the weight across the backpanel, and allows for air to flow between the pack and our back for enhanced comfort.
