This listing is for those customers who wish to add chin straps to any Blue Corduroy sun hat that does not already have chin straps attached. They will be made from a 3/8" cotton twill tape in a natural color. They will be long enough to tie under the chin. ***Blue Corduroy is now offering FREE SHIPPING on all domestic orders!*** Find me on Instagram! @emily_BlueCorduroy Sign up for my newsletter for 10% off your first purchase! http://eepurl.com/vcqe5
