BAYFLOW Fleece Back Blue, but the color is closer to green. #s_kids summary What is pigment processing? It is a dyeing method that adheres pigments to the surface of the fabric, unlike dyes that penetrate the interior. The color fades with repeated washing, creating a unique faded look and vintage feel. It features a worn-in texture (shadows and a brushed feel) as if it were old, even though it's new.
