When you love the Airstream brand, you need a lightweight pullover that can take you from bluebird morning to campfire night, with dozens of adventures in between. A brisk morning hike. A trek to the farmers' market by bike. Brunch in an air-conditioned diner. A nap in the hammock after lunch. A cookout in the evening chill and the thrill of star-gazing. Carry along the crewneck pullover that can carry you through all of your Airstream expeditions.
