Using this hip bag is a breeze. First, adjust the waist belt using the Pull - Forward system to get a comfortable fit. You can put your cell phone and other small valuables in the waist - belt pocket for easy access. The mesh pocket is great for items that need a bit of air circulation. The main zippered compartment is perfect for your 1.5 - liter hydration system. When you're done with your bike tour, empty the bag and wipe it clean with a damp cloth. Store it in a cool, dry place. Avoid using harsh chemicals on it to keep its quality intact.
