Drink Up
Altitude plus exertion equals dehydration. But lugging a metal or plastic bottle up the hill is a hassle. And disposable water bottles aren't the answer-up to 60 million a day end up in landfills. The new Vapur Anti-Bottle ($9) is a nice solution. The reusable bottle stands upright when full and can be folded away in your pocket when empty. Made from BPA-free plastic, it's super light-weight, freezable, dishwasher safe and holds 16 ounces.
