A breathable long-sleeved cut-and-sew top made of stretchy, easy-to-move-in material with a geometric pattern. - Brand: GapFit - Size: XS - Design: Geometric pattern - Color: Multicolor (red, blue, green, yellow, black, pink) Thank you for viewing. I purchased this at a Gap store when they still had physical locations because I loved the color and design. The long sleeves have thumbholes at the cuffs, allowing for a secure fit. It seems to be from Gap's sports apparel series.
