Flannel hardly needs an introduction, but when it’s been retooled to be softer than ever and stretchy—well, we had to say something. We gave this upstanding, lightweight flannel the full comfort treatment, crafting it with double-brushed organic cotton and a hint of spandex to move easily with you, then gave it a vintage garment wash to upgrade the softness even further. A lightweight construction adds seasonal warmth under a vest or a puffy, but won't overheat when worn indoors.
