Using this daypack is a breeze. First, adjust the height - adjustable chest belt to fit your body for a more comfortable carry. You can use the carrying handle for short - term lifting. When you have less stuff inside, use the two compression straps around the pack to make it more compact. The MOLLE system on the front and sides is great for attaching extra pouches or gear. For hydration, just connect your compatible hydration system. As for maintenance, keep it clean by wiping it with a damp cloth regularly. Avoid sharp objects that could damage the CORDURA® 700 den material. If it gets wet, let it dry thoroughly before storing it to prevent mold growth.
