Regardless of the material your hockey stick is made of, it still needs to be taped before you go out to play with it. With the right amount of tape, you can create an excellent knob at the handle for a good grip.
It is not uncommon for moisture to accumulate on the blade of a hockey stick when it is in use. This can negatively influence your gameplay. However, when taped, the blade is protected from moisture. Tapes are also required for some other gear like the shin guard and the socks.
Since tapes became essential for hockey players, so many different types have flooded the market.
