Using your Trekmates Stuff Sack is a breeze. First, open the one - touch free - flow drawstring closure. Then, stuff your items like sleeping bags or clothes into the sack. The bottom handle can be used to hold the sack firmly while you're packing. When you need to get something out, just grab the handle to make it easier to extract your items. As for care, avoid using harsh chemicals or abrasive cleaners. A gentle wash with mild soap and water is enough to keep it clean. Hang it to dry in a well - ventilated area away from direct sunlight. Also, try not to over - stuff the sack to prevent any damage to the material.
