"With its penchant for solid colors (and the occasional stripe) and classic silhouettes, Everlane makes tons of mix-and-match travel essentials. The Cashmere Stroopwafel turtleneck and Dream Pant are some of our readers' favorites, but we'd also point to the Perform legging, Re-Track barrel sweatpant, and Felted Merino half-zip as great long-haul flight pieces."
