One of the best things about the Airstream lifestyle is being able to go "wherever the four winds blow," as founder Wally Byam said. Of course, if the wind does actually blow, you'll be glad that you have this lightweight windbreaker. It's also water-resistant, just in case that breeze brings a bit of precipitation as well. With both a quarter-zip neckline and side-seam zipper plus side vents, you can easily slide it off when the sun reappears. Because nothing forces an Airstreamer to stand still for long!
