A water bag and a water purifier are the essential equipment for overnight hikers. “PURE HIKE” combines the water filter with the water bag that makes hikers easier to get clean water and drink. Hikers wear “PURE HIKE” around neck like towels so that they can see how much water they have. By pressing the water bag, water flows through the filter to the bottle and becomes the clean water.
