How to use: First, adjust the straps according to your body to ensure a comfortable fit. The detachable daypack can be used for short trips or day outings. Just unclip it and go. For long - term travel, pack your essentials neatly in the main compartment. When it comes to safety, use the built - in safety features like reflective strips at night. Maintenance: After each trip, empty the pack and let it air dry. If it gets dirty, gently hand - wash it with mild soap and water, then air dry again. Avoid using harsh chemicals. Also, store it in a cool, dry place when not in use to keep it in good condition.
