Any wardrobe'll benefit from a crisp, well-made long sleeve. Bread & Boxers made this crewneck from a thoughtful fabric blend—94% organic cotton and 6% elastane—which means it's extra stretchy and equally comfy. With a tailored, slim fit, it'll look tidy and put together if you wear it on its own, but works just as well layered under a chunky sweater or a light jacket.
