From the Bog Dog team:
Whether it’s zipped up to its scuba-style hood, conveniently strapped to your hand with its built-in elastic bands or completely forgotten in the corner of your hydration vest, the Skyflow Wind Jacket is designed for adaptability in fickle conditions. Made of light-but-tough Aeroshell™ material, it’s water-and wind-resistant and built to take the knocks of trail life. And with its streamlined, minimalist design, it packs into its own pocket for easy storage.
