From the manufacturer

When you're out under the sun, over reflective waters, for extended periods of time, this is the hat you want. Offering your head, face and neck UPF-50 protection from harmful UVA/UVB rays.

Our integrated signature Omni-Wick sweatband actively breathes and wicks sweat away from your brow for cool-wearing comfort.

Designed for adults and youth, the adjustable drawcord toggle sizing system does away with snaps and velcro, for the perfect fit.

Columbia’s attention to detail is what sets our apparel apart. Specifying only the highest quality materials, expert stitching and craftsmanship, you can be assured that this hat will provide protective and long-lasting service.

Omni-Shade | Sun Protection

Be safe and protected. Omni-Shade blocks UVA and UVB rays to help prevent sunburns and long-term skin damage. The tight weave construction with UV absorbent yarns block the full spectrum of harmful UV rays.

Omni-Wick | High-Performance Wicking Fabric

The ultimate moisture management technology for the outdoors. Omni-Wick quickly moves moisture from the skin into the fabric where it spreads across the surface to quickly evaporate—keeping you cool and your clothing dry.
