Seattle Pilots Uniform History
The Pilots played just the 1969 season in Seattle before moving to Milwaukee.
1969 Spring Training
Apparently management feared the team's jerseys might not be ready in time so a plain-vanilla set is made for the first spring training.
Wilson
1969
Wilson (Home), Spalding (Road)
For the regular season the Pilots debut a unique, distinctive look.
The MLB 100th Anniversary patch was NOT used on the home jersey.
1970
McAuliffe Uniform (Home)
1970 sets were made and shipped to the team, but of course, never worn. Some were probably recrested as the Brewers.

After the 1969 season the Pilots relocate to Milwaukee.
