Using this hip pack is a breeze. First, fill the 1.5L hydration system with your favorite drink and place it in the pack. Put your tube and tools in the available space. When you start climbing, pull the string to increase the back distance for better comfort. As you head downhill, pull the string the other way to tighten it to your hip. When it comes to maintenance, empty the hydration system after each use and let it dry to prevent mold. Wipe the pack with a damp cloth regularly to keep it clean. Be careful not to overfill the pack as it may affect the Ventiflap system's performance.
