Lightweight and 100% waterproof, the Outback Storm Hat is breathable with a structured fedora silhouette. Fully seam-taped with a PFAS-free durable water repellent (DWR), this classic style has a Reverse Split Brim™, which means it packs small and flat. The crown is crushable, so this hat never loses its shape. The UPF 50+ sun rating makes it a stellar choice by day, and reflective piping is handy when the sun goes down. The adjustable chin strap keeps your hat in place when adventures get breezy.
