If you are in between sizes, we recommend sizing up. If you have sized up, we recommend using hat sizers to ensure the perfect fit. To insert the hat sizer, remove the adhesive back, place them evenly inside the sweatband so they are hidden, and adjust until you have found your perfect fit. Made of 100% wool. Available in black and off-white.

Application: Place wool strips on either side of your hat underneath the sweatband, with the adhesive side facing towards the sweatband. Adjust as needed.
