SurvivalHax.com sells products perfect for survival, emergencies, camping, and other activities in the great outdoors. It’s always a good idea to be prepared for any situation, especially when you are a parent. In addition to the standard first aid kits, blankets, etc. water is a very important necessity to have on hand. Sure you can carry a few spare bottles but it’s also good to have a back up plan if you run out. Not only that but if you stock it by the gallon it becomes very heavy to carry around. This product is very light and allows you collect water from nearly any stream or body of water in case of an emergency. The filter lasts a very long time and you don’t have to use it with this bottle. It has a universal cap that attaches to any standard water bottle spout. As a bonus they also threw in a carabiner keychain and a manual fire starter in this kit.
