Hat Care Kit
The key to keeping your hats looking fresh is by routinely maintaining them. Our Hat Care Kit makes it easy to do just that!
Premium Ready-To-Use Hat Cleaner
Jason Markk Ready-To-Use Hat Cleaner is a fragrance-free solution specifically formulated to gently, yet effectively clean hat materials such as cotton, wool, felt, corduroy, polyester and more. This product is conveniently pre-mixed and ready-to-use straight out of the bottle. Simply pump and scrub, no water needed.
Premium Cleaning Brush (AKA Delicates Cleaning Brush)
The Jason Markk Premium Cleaning Brush features soft hog bristles that are excellent for cleaning delicate hat materials. Use dry for daily maintenance, or use with our RTU Hat Cleaner for a deeper clean. When used with solution, rinse with water, shake, stand brush upright and allow to air dry.
The bottle and applicator are fully recyclable. The box packaging is constructed from partially recycled material.

Sizing Guide

Every Citizens of Beverly Hills hat is designed with intention, but fit can vary by style.
Our caps are built around a standard 58cm fit, with a small natural variance of ±0.3–0.5cm. Each hat features an adjustable back closure so you can dial it in to your preference. Every notch increases the size by roughly 1.0cm, allowing the fit to expand up to approximately 60cm when fully adjusted
