The Eagle HYDRO: A New Shape, Perfected

The Eagle HYDRO: A New Shape, Perfected

When we start the journey of building a new shape, it always starts with questions. Of course there are the easy starters… How should this fit? Who is it for? What materials should we use? What technologies should be included? But some of the most important questions we ask are how should this make you feel when wearing it? How should it move with you? What problems are we solving with this new shape?


The Eagle HYDRO is the result of answering those questions over and over again. It’s an all-new shape built with the same obsession with detail that defines everything we make, just lighter, more comfortable, and designed for real life.


This isn’t about reinventing headwear. It’s about refining it.


An All-New Fit, Designed to Feel Effortless

The Eagle HYDRO features an unstructured fit, giving it a relaxed, natural feel the moment you put it on. There’s no stiffness, no break-in period, just comfort that adapts to you.


This unstructured construction reduces overall weight while allowing the hat to dry faster and travel easier. Toss it in a bag, wear it all day, throw it in your backpack. The Eagle is built to handle movement without losing its shape or comfort.


Cloud Visor Core: Contoured for Comfort

At the heart of the Eagle HYDRO is our Cloud Visor Core, the lightest and most comfortable visor we’ve ever engineered.


By welding a thin layer of our proprietary resin-based visor core with ultra-light EVA foam, we created a visor that holds its shape while adding flexibility and dramatically reducing weight. The result is a visor that feels almost weightless but still performs when it matters. It bends when you need it to. It holds when it's your perfect style.


Built for Movement, Travel, and the Elements

Every detail of the Eagle HYDRO is designed with real-world wear in mind:

  • Full Rear Panels: Fully crushable for travel, fully protective from the sun.

  • Thumbprint Undervisor Seal: Gel-Welded to the bottom of the visor for added durability and longevity where wear shows up first.

  • HYDRO Droplet Ventilation: Coated droplets on the rear panels increase breathability while maintaining structure and performance.

  • Tonal Branding: Minimal logos let the construction, materials, and shape speak for themselves. Clean. Refined. Purposeful.


And yes, like every HYDRO hat, the Eagle remains water-repellent, antimicrobial, and engineered to be the most durable hat you can buy.
