Shop Seattle Mariners Hats at Fanatics

As the officially licensed MLB destination, Fanatics carries Seattle Mariners hats across every major style, fit, and colorway. Whether you wear a structured fitted cap on game day or keep it casual with an adjustable everyday lid, every hat ships directly from an authorized MLB partner. Styles are available for men, women, and kids.

Finding the Right Seattle Mariners Hat

Start with fit. A fitted cap delivers a clean, tailored look — New Era 59FIFTY silhouettes are the standard here, sizing by full and half measurements for a precise result. If you prefer flexibility, snapbacks and strapbacks from '47 offer a broken-in aesthetic with one-size versatility. For a lower crown and streamlined profile, the mariners low profile hat category draws fans who want a subtler silhouette that still carries official team marks. Colorways span navy, black, white, cream, brown, and gray, while specialty drops — including City Connect and throwback designs — reflect different eras of M's identity. Kids can find youth-sized options engineered for smaller heads without sacrificing authentic team details.
