Using your Subterra 2 Backpack is a breeze. First, use the interior organization panel to neatly arrange your small items like keys, pens, and chargers. Place your laptop and tablet in the padded sleeves for maximum protection. When you're carrying the backpack, adjust the straps so that it sits comfortably on your back. For long - term use, try not to overstuff the backpack as it may damage the internal structure. To clean it, use a mild detergent and a soft cloth. Gently wipe the exterior and interior, then let it air - dry. Keep it away from sharp objects to prevent scratches. With proper care, your Subterra 2 Backpack will serve you well on all your travels.
