Collapsible bottle is easy to pack

WHAT The Vapur Anti-Bottle

HOW MUCH $15.99 for two.

WHAT IT IS A 0.4-liter (about 9 ounces) reusable water bottle made of heavy, flexible plastic. Actually, it's more of a water bag, since it collapses when empty.

WHAT'S GOOD From a convenience standpoint, the Anti-Bottle has much to offer. It chills easily (the thing is even freezable), it's lightweight (nice for runners) and it can be rolled up when empty for easy transportation. From a green standpoint, you're not adding to the mountain of plastic bottles that get tossed into the trash every day. These also are BPA-free and dishwasher-safe, and come with a carabiner for clipping to your pack, purse or belt loop.

WHAT'S NOT Don't get too thirsty. At 9 ounces, this doesn't even qualify as pint-size. The nozzle is likewise smallish.
