Sizing Guide

Adjustable Fit. Designed for Comfort.

Most Harrington & Co. caps are crafted with a discreet adjustable band, allowing the fit to adapt naturally and securely to your head.

These adjustable styles comfortably fit head circumferences from 52 cm – 62 cm (20.5in – 24.4in), covering virtually all adult sizes.

Select styles are offered in fixed sizes for a more traditional fit. For these, you’ll be able to choose your size directly on the product page. A detailed size chart can also be found below the product description.
