We love hats, we love wrap around earmuffs, we love all head gear. The only thing we don't love is over heating or hair that can't be fixed after wearing these items. Functional Fashion SunMuffs are adjustable earmuffs that attach to any eyewear with stretch, no slip loops. Wear your sunglasses or prescription glasses with SunMuffs. Being attached to eyewear keeps the earmuffs from falling off and keeps them perfectly comfortable.
