Sawyer Products SP2101 MINI Water Filtration System, 2-Pack, Blue / Green

I haven't used it as I got it for a Christmas present to a young couple in case of emergencies. The power around here goes out at least a couple times a year. And I think everyone should have a way to make sure they have clean drinking water. ... I carry a Sawyer in my pack at all times. And with Sawyer's reputation, I thought it would make a nice Christmas gift. Hopefully I'll never have to report how it worked.

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.
