Collapsible bottles are flooding the extreme sport market, and because we take a Pilates class and run
three times once a week, of course, we have to have one. The Platypus plusBottle ($17) tops our list, seeing as it's favored by all sorts of adventurous types. Seriously, though, even if you just need something that fits into your purse as opposed to a camping pack, this is it. And the Platypus is made of tough stuff, able to endure both freezing and boiling temperatures.
