The smartest trend of the moment is hyper-light backpacking. The point is to be as minimal as possible, using only the lightest and most essential materials. That's where California-based outdoor company Vapur comes in. Flexible and brilliantly-conceived, Vapur makes portable, hand-held hydration products that they call 'Anti-Bottles.' Less of a waste than disposable bottles and lighter and more compact than bulky metal or hard plastic, the Anti-Bottle wraps up and flattens when not in use. In keeping with its commitment to the environment, Vapur contributes a portion of its sales to water-related and environmental causes.
