Sometimes a little extra protection can go a long way. If the skies look like rain might be in the forecast but not a total downpour, that's when you'll be glad you have the Zephyr Vest from Giordana to keep your core warm. This semi-transparent lightweight vest keeps wind, fog, and wheel spray from ruining the ride and adds some insulation on extended descents. It's important to note that this isn't a completely waterproof piece as it lacks taped seems, however, it's extremely water resistant. Our favorite feature of the Zephyr Vest is its ability to be easily packed into its built-in pocket and stowed into your jersey pocket until its needed. Perfect for those unpredictable spring and fall days when you don't need something cumbersome during your intervals but enough to knock the chill off on the way back down the hill to begin another repeat. The vest features reflective accents on the back as well as fluorescent trim and at the zipper to help aid visibility in low light.
