On Nov 24, 2009, the Mets announced a new alternate uniform for the 2010 season that is reminiscent of the 1962-1970 Mets uniforms. Apparently these jerseys will feature a cream color similar to those of early flannel material.
Here is a picture of the depicted polyester jersey. It is on sale at the Mets website and Team store for a retailed $194.99
Here is the ‘official’ word per the New York Mets media outlet:
“The design combines new and old elements of Mets uniforms. The Mets created the retro uniform following research and positive responses to the jerseys the 1969 World Champion Mets wore during their 40th anniversary celebration in August… The natural color and pinstripes were staples of the original Mets uniform when the team debuted in 1962. The Mets will also continue to wear their white uniform at home with the black jerseys as an alternate.”
