Things I liked:Seems to work as advertised. Things I would have changed:I'm with the several other reviewers who call for a better (larger and non-leaky) conainer. I think a 1 ounce bottle would be about right.
Things I liked:This is a really neat concept and I'm very happy with mine. I had been wanting a 1322 but this is much better. Things I would have changed:The backpack needs to have a dedicated posket for the water bottle.
