"After interviewing three dermatologists, an ultra-runner, four ultra-hikers, and field-testing a total of 200 hours, we’re convinced the sun hat that works best is the one you’ll actually wear. A unanimous favorite among our testers, the Sunday Afternoons Ultra Adventure Hat provides the best balance of coverage and breath-ability, and is unobtrusive enough that you can forget you have it on." As written in The Wirecutter.
Hear that? It’s the call of the wild—don’t forget your Ultra Adventure Hat! The Ultra is updated with a slimmer silhouette and fun technical details like our Clamshell Brim™ and Sunglass Lock™, but still retains the sun protection, ventilation, and moisture management of our iconic Adventure Hat.
