How to use: First, adjust the continuous - wrap harness and hipbelt to fit your body comfortably. Place your hydration reservoir in the sleeve and make sure the tube is accessible. You can mount your ice axe, trekking pole, bike helmet, or blinky light according to your needs. When you go on an adventure, just put on the pack and start your journey. Note: Don't exceed the maximum carry weight of 8 kg / 20 lbs. Avoid sharp objects that could damage the pack. Maintenance: After each use, air out the pack. If it gets dirty, use a mild detergent and a soft cloth to clean it gently. Then let it dry naturally in a well - ventilated area.
