Just about the only thing the Seattle Mariners shared with the Seattle Pilots- aside from Diego Segui- was the traditional nautical-themed blue and gold color scheme.  The Mariners, however, took it a step further and included a trident in their primary logo.  Pointed down to mimic the letter "M," many superstitious individuals derided the "upside-down" orientation of the trident, which was said to "let all the luck run out."  The reality was the Mariners wouldn't have a whole lot of luck on the field in their early years, and it would take them 15 seasons to post a winning record.  

          The Mariners made their debut during the height of the double-knit era of polyester pullover jerseys, but managed to keep their design relatively simple in the face of what many other teams were wearing at the time.  At the very least, they were more popular with players than the '69 Pilots uniforms, which pitcher Jim Bouton once described as "clown suits."

          The home jersey in 1977 was a white v-neck pullover, with the player's name on the back sewn directly to the jersey; the pants featured a striped, elastic waistband closure that most teams wore at one time or another during the 1970s and '80s, along with royal blue stirrups.  The team would keep this style from 1977-1980 with no notable changes.  Mariners teams in 1997 and 2007 would wear this design again during special "Turn Back the Clock" events to mark the 20th and 30th anniversaries of the team's debut.  (Maybe in 2017, for the 40th anniversary, they'll get the waistbands right like they did in '97.)

          The away uniform, on the other hand, would see a more significant change between 1977 and 1978.  For the 1978 season, the jersey lettering changed from navy on white to royal on gold, and used a slightly different typeface.  Additionally, the striped trim pattern around the neck, the cuff of each sleeve, and the waistband was altered.  This style would continue through the 1980 season.

          In 1979, Seattle and the Kingdome hosted the 50th Major League Baseball All-Star Game.  As is still the practice today, there was a custom logo developed to promote the event.  During 1979, the Mariners wore a version of this logo as a sleeve patch on their jerseys.  The sleeve patch remained on the left sleeve during the 1980 season, as well, and would go on to even bigger and better things in 1981.

          The Mariners' uniform suppliers from 1977 to 1980 were Wilson and Rawlings.  Dugout jackets were supplied by Starter.  Caps were provided by New Era.
