Our take · Researched, not tested

Two Velcro sizers that take a hat down a full size.

By Walt Mercer, felt, fit and care desk Pen name, fact-checked by our team

A hat that's a size too big can be rescued. These full size reducers come as a pair of Velcro-attached sizers made for non-felt hats. They attach at the hat's front with Velcro buttons, which reduces the fit by a full size and adds some cushion. They work as replacement sweatliners too.

Walt's tip: Fit one sizer first and try the hat on. Add the second only if it still slips, and use the half size version for finer tuning.
