A good shortsleeve buttondown for women is hard to find. A good chambray that isn't scratchy or stiff is even harder to find. Guess what? We done did both, and put them together in this shirt. 100% tencel. We like to tencel because it's made of wood, so it's eco-friendly. It also has a really smooth fiber surface which as you could probably guess, makes it absurdly soft.
