Coolibar is the world leader in UPF 50+ fabric technology.

For more than 20 years, Coolibar has been innovating UPF (ultraviolet protection factor) 50+ fabrics and UPF clothing guaranteed to block 98% of UVA/UVB rays, providing UPF 50+ sun protection clothing you to wear. As a result, Coolibar was the first clothing company to receive The Skin Cancer Foundation's Seal of Recommendation.

Our research, experience, and dedication to the science of sun protection clothing, UV performance fabrics and styles are the basis for all our products. Our UPF sun protective clothing, sun hats, and sun protective swimwear provide the highest UV protection available to keep you cool, comfortable, sun safe and looking good. It's like effortless sunscreen you wear.

Rigorously tested and recommended by dermatologists worldwide - Coolibar guarantees UPF 50+ protection for the life of the garment as set by ASTM/AATCC standards. Coolibar tests every fabric in every color and every pattern against multiple standards before we ever stitch a garment. We measure all fabric performance against the Australian New Zealand UPF testing standards, the world's highest rating standard, as well as U.S. standards. Coolibar's level of sun protection exceeds all published rating standards of UPF 50, yet because the industry standard for certification stops at UPF 50, we indicate that we go above and beyond by using the "+" symbol.

Summer weight fabrics let through an astonishing amount of the sun's damaging ultraviolet rays; they usually protect less well than an SPF (sun protection factor) 30 sunscreen. For maximum UV protection and skin coverage, we recommend UV Rash Guards, UPF Swim Tights, UPF clothing and UPF 50+ sun hats, the perfect UV light shield from the suns rays.
