Using your Thule Subterra 2 Sling Bag is a breeze. First, decide how you want to carry it. You can wear it cross - body for better stability during movement or as a hip pack for easy access at all times. If you're going on a long trip with a larger backpack, use the stowable strap to convert the sling bag into a packing cube and tuck it inside. This way, you can keep your essentials organized within the bigger bag. When using it alone, take advantage of its modular features to arrange your items just the way you like. As for maintenance, clean it with a soft, damp cloth regularly to keep it looking good. Avoid using harsh chemicals as they may damage the bluesign - certified materials. Also, be careful not to overstuff the bag as it might affect its shape and functionality. Keep it away from sharp objects to prevent tears or scratches.
