The Sawyer Mini Straw is a great water purification device that you should have in your emergency kit, or to take camping. Many time, people will have some kind of water bladder system, such as a Camelbak. Both of these are great ideas for your venture: water purification and mobile water storage. I remembered reading something at one point that hinted at being able to attach your water filter to the straw of a bladder, in essence purifying the carried water. I was unable to figure this out, but then I found this! Below is a great video that perfectly shows you how to attach the Sawyer Mini to either a Camelbak, or to another bladder. This video is well done by a group called Zulu Team 6. Check this out!
