This cap comes in 3 thicknesses - the XS uses the thinnest material for extra breathability and the S uses a medium thickness, slightly thicker than the XS, and the M is again slightly thicker to withstand anything a tiny toddler throws at it.
CLOSURES AND TOP BUTTONS
All caps have a velcro fitting for extra comfort.
