To use the Baggu Duck Bag, simply place your items inside. You can use the interior zip pocket to store smaller, more important items like keys or a wallet. You can carry it by the top handle for short trips or adjust the 40' strap to wear it over your shoulder for longer outings. When it comes to maintenance, it's easy! Just toss it in the washing machine. However, make sure to zip up the interior pocket before washing to prevent any items from getting lost. Also, avoid using harsh detergents that could damage the 16 oz recycled cotton canvas. After washing, let it air dry. That's all there is to it, and you'll have your trusty Baggu Duck Bag looking great for years to come.
