Looks like a long sleeve, feels like a cloud. The Flyout™ fabric with HoverFit® technology is so lightweight, and uniquely knit, that it hovers above your body - easily managing the movement and evaporation of sweat. This means that it feels incredibly light, but wears like a protective layer when you need it. Raglan design, ultra soft hand feel, thumb holes and a signature hem line brings it all together. Plus, enjoy Oiselle's signature Watch Window, so you can track your workout without yanking up your sleeve! - HoverFit fabric (polyester/tencel/spandex) - thumbholes - watch window on both sleeves - unique side-seam finish - constructed with Bluesign Approved Fabrics
