Whether you have a bet going, you're competing in a contest, or you're just plain curious, you can track all the data from your last in-bounds or backcountry adventure with the Zeal Z3 GPS Polarized Photochromic Goggle. That's right--it's a vented goggle that protects your eyes, changes tint according to the conditions, and displays and records information from your runs. And, of course, you get great optics, too. We can't think of any other functions you could possibly stuff into one pair of goggles.
