Update to our classic scrub cap style with the Advantage by Butter-Soft Unisex Scrub Cap with Adjustable Hem. The cap has an open back which allows better fit and comfort. The drawstring at hem keeps the hat firmly at place and also creates a comfortable fit for a long day. The scrub hat is made of 75/22/3 poly/rayon/spandex twill weft side stretch. One size fits most.
