i ordered a S/M which is a bit too snug (i'm petite). the mask piece can be pulled down easily but a struggle to tuck it back in the hat. i give it 1 star for the warm and soft material and sturdy construction. my biggest problem with it is it is pointy on top, in front, and on back of my head once i put it on. it does not form a round contour as shown on the model pictured in the tag.
