Without good wide brim sun hats, the skin on your face, scalp, and neck will be exposed to damaging UV rays whenever you’re outside—even when it’s overcast. Coolibar floppy sun hats are made from revolutionary sun-safe fabrics that block up to 98% UV. And they roll up small and travel well, so they’re ready whenever you are.
