What is DayBasics fabric?
Soft, light and easy to live in.
DayBasics is a lightweight fabric with a smooth, cotton-like feel that's gentle on your skin. It's light and breathable, so it's easy to lounge in on a warm afternoon or sleep in on a beach vacation. It folds light and flat in your carry-on, resists pilling, keeps its shape and goes straight in the washing machine. It's made from our fine 100% polyester microfabric: everyday softness without the weight or the fuss.
