Soft fabric that is light and thin to keep cool, but it pills a lot easily along the sides from your arms rubbing. Love the Aqua colour, not too bright but not too pastel. Love that the colours match a lot of the other shirts for layering. The fit is small, I always get a size up for all their jersey things (cami, tank, tee). I wish there was petite sizing because I find the straps too long making the neckline too low, barely covers my bra.
