This one slipped right by me! Chaim announced on the Catrike forums about three weeks ago regarding the (then) immediate availability of official Catrike jerseys. They feature the Catrike and, oddly, SolidWorks logos on the front with a trike outline on the back. The jersey is produced by Primal Wear and is a club cut. The pockets are 3.5" x 5".
Price is $79, available only in blue, and can be ordered directly from Catrike.
