I could be wrong but I think almost all MLB teams are using cool base jerseys (home and road) during games not just BP. I know the Yankees use cool-base for BP and do not use cool base for regular games. I don't believe the Yankees are using the cool flo helmets either.
Correct me if i'm wrong.
yes i was looking at auctions for Yankee BP shirts thru steiner awhile back.
