Arobello Polo We take athleisure to another level. Our sun-smart long sleeve polo has elevated design details like a hidden placket and thumbholes, for a sharp look on and off the course. And thanks to our buttery soft, textured UPF 50+ fabric, you’ll want to wear this lightweight performance polo everywhere. Technical. Elegant. Sun Protection You Wear. Our fabrics are rigorously tested and recommended by dermatologists worldwide. We test our fabrics more than any other brand. Only Coolibar conducts multiple tests for factors affecting UPF rating during normal wear and washing including fabric color, weave, shrinkage, stretching, coatings, chlorine, salt-water, and laundry detergent. Our Mission... Is to keep the world safe from sun damage, protect those who suffer from a sun-related medical condition and prevent everyone else from developing one. For more than 20 years, Coolibar (koo-luh-bar) has stopped at nothing to develop the most technical and elegant sun protective clothing, hats and accessories. In fact, we are the first sun protective clothing company to receive The Skin Cancer Foundation’s Seal of Recommendation.
