WCF Product Code¶
The World Curling product code is on the underside of the label sewn into your competition sleeve.
Turn the label over to read it. The example below shows S1A1A; your sleeve may carry a different valid code as World Curling assigns new approvals.

A competition sleeve needs a valid product code to form part of an approved setup. You can check the current approved code list in World Curling's equipment reference.
The sleeve is one part of the setup. Check Competition Use and Checking Your Foam before competition.
