How to use: First, open the main compartment to store your daily essentials like books, notebooks, or clothes. Place your laptop safely in the dedicated laptop section to protect it from bumps. Keep your sunglasses in the fleece - lined pocket to prevent scratches. Adjust the breathable straps to a comfortable length before wearing. Note: Don't overstuff the backpack as it may damage the structure. Avoid sharp objects near the backpack to prevent tears. Maintenance: Regularly clean the backpack with a damp cloth. Let it dry thoroughly before storing. If there are stains, use a mild detergent and gentle scrubbing.
