Crazy Scrubs is the largest colorful hat manufacture in the world! Our hats have been seen on The Discovery Channel, ER, and Entertainment Tonight. We proudly donate our hats to medical missions around the world. There is a pleated flat band in the front of the hat that is lined with terrycloth to keep you cool and comfortable. The back of the hat has an adjustable toggle making it feel just perfect and not too tight. 100% cotton that will not shrink or fade. One size fits all.
