This is a shallow knit cap from Uniqlo. It doesn't contain acrylic, which tends to pill. It feels nice to the touch. It's soft and gentle, and doesn't feel scratchy. It has a cable knit pattern? I don't know what kind of knit it is, but the pattern is cute. I bought it to wear discreetly under a thin, cold hat in early spring to keep warm. I think I bought it around 2010. I probably used it 3 or 4 times around then? I've stored it for a long time after home cleaning. It's not extremely tight, but it does have a bit of a snug fit (Mongol's head isn't small). Mongol is unusually sensitive to tightness and pressure, so it should be fine for most people. The color is black. It's a material and color that tends to show dust. I don't see any pilling or fuzzing in particular, but it does have a slightly fuzzy look, which is typical of yarn. I can't completely remove the dust, so I'll send it as is. Color: Black
