Using the Lobo™ bike pack is easy. First, fill the 3 - liter Crux™ reservoir with water and connect it using the Quicklink™. Put your essentials like snacks, tools, or a small jacket in the 9 - liter storage space. When you're riding, just take a sip from the reservoir's tube to stay hydrated. As for maintenance, after each use, empty the reservoir and let it dry. If it gets dirty, wash it with mild soap and water. Avoid using harsh chemicals. Store the pack in a cool, dry place when not in use to keep it in good condition.
