Vaavud Wind Meter

At well under 1oz and below $50, raise a cup (two, actually) to the wind on your next excursion. While toy-like in appearance, this gadget's app makes the easy-carrying Vaavud a no-brainer for smart phone- and tablet-toting hikers and skiers. Active Junky’s sold on this inexpensive trip-saving tool that captures and tracks data like a pro for 1/3 the cost of dedicated weather instruments.
