Those hours might be few and far between, but once you realize you have some free time you're already filling up the Hydrapak reservoir inside the Vital 3L Hydration Pack, and rolling your mountain bike out the door. The Hydrapak reservoir has a clever ReTrakt hose that offers hands-free retractability as soon as you're drinking. The 3L compartment includes a zippered pocket to separate your valuables from your downhill essentials. Thule positioned the side pockets so you can get a water bottle or energy bar with the pack on.
