Here's a sun protection parasol that's elegant enough for an outdoor wedding yet functional enough for everyday use. Our Calotta Fashion Umbrella, like all Coolibar sun umbrellas, is designed to deflect the sun's damaging ultraviolet rays to keep you noticeably cooler on hot, sunny days and shed rainwater, too! For Silver - Silver color on the outside to reflect UV rays, green on the underside to absorb UV rays. For Black - Black color on the outside and inside.
