Andy Murray Wears Scottish Blue at Indian Wells.
Looking for Andy Murray's shirt at Indian Wells? It's the Fred Perry US Open T-shirt in Scottish/Blue, $52 USD. Not new but nice looking for sure and still available. It's made of Activair fabric designed to keep you cool and dry and contains 38% recycled polyester (file that under green effort).
Find a retailer at Fred Perry. You won't find the shirt on their site OR a mention of their winning ambassador. Strange. Tennis Express carries the shirt in the U.S.
