Seattle Mariners Caps History

Seattle returns to the AL in 1997 after an eight year absence. Thanks to collector Mike C. for a bunch of these photos.


The Mariners colors are blue and gold like the old Pilots, the cap is the famous pitchfork M.

New Era


Cap logos become a trident M over a star.

1981 era caps have the logo embroidered. Mid-80's caps have a sewn on patch that gives a 3D-like appearance.

Sports Specialties

Sports Specialties caps are worn by some players in the mid-80's.


A more traditional look is adopted in 1987. The cap logo is a simple S.

Some players start using grey undervisors around 1988. By 1990 all players use them.

By now all caps have grey undervisors. In 1992, MLB logos are initially glued on the back, then embroidered later on in the season.

The Mariners swap gold for teal, royal blue for navy, and introduce the compass S logo. Home caps have teal visors, road caps are solid navy.

These gold tags and taping appeared in some caps in 2004 to mark the 50th anniversary of the introduction of the New Era 5950 cap model in 1954. I don’t see many of these from on-field only because not many were made, and players kept them as souvenirs.


Caps go polyester.
