The back of rugby jerseys can have different things depending on the team and the purpose. Here are some of the things that can be found on the back of rugby jerseys:
-
GPS tracking device: This is a small rectangular lump that can be found on the back of some rugby jerseys. It is a GPS tracking device that provides incredibly detailed performance data, such as where the player was at any point in the game, how much ground they covered, and their average speed. The data can help both professionals and amateurs improve their performance.
-
Padding: Some rugby jerseys have padding on the back to protect players from collisions and scrums.
-
Special pocket or harness: Professional rugby shirts frequently contain a special pocket, at the top of the back, for the GPS tracking device to be inserted. Otherwise, players may wear a special chest-hugging harness that’s sometimes known as a sports bra.
In summary, the back of rugby jerseys can have a GPS tracking device, padding, or a special pocket or harness.
