Sawyer Products SP101 MINI Water Filtration System, Single, Green

Instead of laying down and drinking through a straw this allows you to fill the bag and drink standing up or while walking. You can use a standard water bottle instead of the bag that comes with it because it has standard threads. You can also attach a straw and use it exactly like a life straw. Finally, you can attach this to the drink tube from most bladders for use with unfiltered water. Sawyer filters, this one included, can be back flushed with clean water. Making Sawyer filters capable of lasting for years instead of one time use. I downgraded Durability because a long term filter should come in a stronger case. If you ever need this device, it would be disaster to find a connector snapped off.

Great filter, adapts to most everything. Had to buy separate more permanent and reliable water bags (VERY expensive but I found a great buy on "EVERNEW" Brand, replacement 1/2 gallon triple layered poly water bags at CampSaver dot com) found the bags with a Google search. they have several sizes available. REGULARLY $40 EACH !!!! I GOT FOR $12.90 EA !!! These water bags are meant to last and are made to readily accept the Sawyer water filters. The clear bags left in the sun for 8 hours kills bacteria, ultra violet light from the sun! Happy Camping!
