The Group by Babaton Utility Button-up is a button-up shirt. This is a modern button up with two chest pockets. It's made with TENCEL™ Lyocell — a wood-based fibre produced through a more sustainable process. Garment Dye (Gd) Colours: The unique colour of our garment dye is achieved through a special process — instead of dyeing the fabric, we dye the finished garment for a dimensional, washed-down look and soft feel. Results vary from one piece to the next, so yours is truly one-of-a-kind.
