Love my new Compass Hydro! The Waikiki sales associate was very accommodating and helped me find the perfect hat for my active lifestyle. I also really appreciate Melin honoring my veteran status with a generous military discount. It has quickly become my favorite everyday and pickleball hat! I’m heading back for another one before going home. Highly recommend!

Love this hat! Was sporting this one my trip in Hawaii! The guys at the Melin shop at the Royal Hawiian Village was very helpful and awesome!

I think I have a new favorite hat brand.
I’m typically picky when it comes to hats. I prefer a very specific fit for my head size and shape and Melin offers styles in different fit options. I found my fit and I can’t wait to buy more colors. The quality surpasses the other brand I’ve purchased over the years.
