There is no baseball city in America that waited the way Seattle waited. The Mariners joined the American League as an expansion club in 1977, and for eighteen seasons the franchise had never played a postseason game. When October finally arrived in 1995, it arrived all at once - and the uniform has been part of that story ever since.
1977: A Team, and a Look, From Nothing
The expansion Mariners took the field in royal blue with gold trim, the palette of the Seattle Pilots who had come and gone in a single season in 1969. The first identity carried a trident-like mark and a script wordmark, and it looked like what it was: a brand-new club still working out what it wanted to be.
1993: The Compass, the Trident and Navy and Teal
The modern Mariners look arrived in 1993 with the move to navy, teal and silver - the colour scheme that still defines the franchise. The new marks paired a compass rose with the trident "S", and the teal immediately became one of the most recognisable accent colours in the sport. It was a genuinely regional identity: north-west water, north-west light.
1995 and 2001: The Two Seasons That Built the Franchise
In 1995 the Mariners forced a one-game tiebreaker for the American League West and won it, reaching the postseason for the first time. It saved baseball in Seattle, and the ownership that bought the club afterwards moved it into a ballpark built for it.
Then came 2001: 116 wins, the highest single-season total in American League history. That team won the division by a margin nobody has matched since, and it did it in the navy and teal that had become the face of north-west baseball.
The Icons and Their Numbers
The Mariners honour the players who carried the franchise. Ken Griffey Jr. - the first overall pick in 1987, 630 career home runs, and the smile that sold the sport to a generation - had his number 24 retired. Edgar Martinez, the greatest designated hitter of his era, had his 11 retired. Ichiro Suzuki, American League MVP and Rookie of the Year in the same 2001 season and the holder of 3,089 MLB hits, had his 51 retired. Randy Johnson and Felix Hernandez anchored the rotation through the best years in club history - Hernandez's perfect game in 2012 remains one of the great single performances in franchise history.
T-Mobile Park and the Modern Uniform Set
The club moved into its retractable-roof ballpark in 1999, and the jersey set has been refined around it ever since: the white home jersey with the navy script, the grey road jersey, the navy alternate, and the teal City Connect design that leans all the way into north-west colour. The compass and trident marks have stayed at the centre of the identity for more than three decades.
2026: Back in the Race
After a 21-year postseason drought ended in 2022, the Mariners have been back among the contending clubs. In 2026 they spent the final week of September deadlocked at the top of the American League West, with the division still undecided and a four-game gap between the top of the division and the teams chasing from behind. Whatever the last weekend brings, the navy and teal are playing meaningful games in September again.
Why the Jersey Still Matters
A Mariners jersey is not just merchandise in Seattle. It is the 1995 tiebreaker, the 116-win summer, the retired numbers in left field, and a city that spends half the year under grey skies and shows up anyway. Ours are fully stitched - the lettering is sewn through the mesh rather than printed on - in men, women and youth sizes.
