Sunday Afternoons Ultra Adventure Hat - Editor's Choice Award, Outdoor Gear Lab, 2017

"The Sunday Afternoons Ultra Adventure is the highest performing hat for high output sunny activities and wins our Editors' Choice Award. We were pleasantly surprised by how protective and versatile this competitor is. We took it on many outdoor excursions, including backpacking and boating tips, and it kept us cool and comfortable the entire time. It's lightweight, quick drying materials are a step up from the Sunday Afternoons Adventure Hat and it is much more durable and packable than that model as well. It has a great combination of sun protection and breathability in a somewhat less dorky package than the other cape style hats we tested."
