As far as cleanliness goes though, I'm not sure a hydration pack is any more sanitary than a bottle unless you use a bite valve cover, and those can be pretty unwieldy on the bike. My experience is that the bite valve is always dragging in something, which is why I use a cover.
I use one all the time and have rarely, if ever, experienced any of those issues. And if anyone ever laughed at me for using my Cambelbak, I'm sure I could find something to laugh at them about in return

The Dream is a good one (though Bicycling is silly as usual in their review of it )

And, hey, this is yet another thread about which I should be grumping about the search function. I must be in a good mood today or something
