The new BSK UV-Pro Beanie Cap offers moisture wicking, cooling and UV30+ protection for those with medium, short or zero hair. Its tri-panel design offers a good fit for all head sizes and a stylish look. The new design now has a hi-visibility trim and logo for a more stylish look. The BSK UV-Pro Beanie Cap is manufactured using a combination of CoolDry? fabric and Spandex for flexibility. The CoolDry? fabric combines the comfort of cotton and the quick-dry performance of polyester fabric. It maximizes the transmission of moisture from the skin to the outer surface of the fabric by a combination of special capabilities. The tetra cross channel cross section of the fiber results in weight reduction of 25% when compared to regular polyester. The tetra channel structure of the fiber makes CoolDry? more breathable, which repels the moisture quicker and keeps the body drier and more comfortable. The BSK UV-Pro Beanie Cap offers a sun protection factor of SPF30+. We still recommend you wear sun block as SPF30+ represents around a 97% of the suns harmful rays being blocked (SPF 15 blocks 93%). Its tri-panel design offers a good fit for all head sizes and a stylish look. Dont be caught without yours!
