The Wilfred Free Weekend Tank is a boxy muscle tank top. This is a crew-neck tank top with a boxy fit. It's made from 100% cotton. 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.
