Nalgene Wide Mouth Canteen

No one wants a ton of water bottles banging around in their backpack.  But at the same time, don't we want a larger amount of water available to us, say at our campsite?  This is where the Nalgene Cantene shines for me.  It is compressible until you need it, durable (I've had this one for over 20 years), *BPA Free* and even stands up on its own.  Whether you are backpacking, on an overland adventure or just carrying around some extra water in the back of your car, this may do the trick for you.
