How to use: First, unzip the compartments to start loading your items. Use the main compartment for larger stuff like books or clothes, and the front compartment for smaller essentials such as keys or wallets. Attach your modular gear to the webbing on the sides. The concealment pocket can be used to hide important items. Adjust the shoulder and waist straps for a comfortable fit. Attention: Don't overstuff the compartments as it may damage the zippers or the bag's structure. Avoid sharp objects near the bag to prevent tears. Maintenance: Regularly wipe the bag with a damp cloth to keep it clean. If it gets wet, let it dry naturally. Check the zippers and straps periodically for any signs of wear and tear.
