I was actually not sure how they manufacture this, so I looked it up on their site:
For our basic mens, womens & kids apparel we use direct to garment printing, which involves applying a pretreatment before loading the garment into a printer. This ensures the prints sink into the fibres of the textile, making them much more long wearing than traditional ‘transfer’ prints, which just sit on top.
Our full bleed range, which includes products like the graphic tee, leggings, scarf & A-line dress are created using a different technique called sublimation printing, which uses heat sensitive inks. Under heat, these inks turn into gas and combine with polyester textiles. Since the ink becomes part of the structure of the material, the images on the fabric don’t fade or crack, even after many washes.
