Unifiber - HD RDM Carbon Mast Extension (U-Pin)

As the name says, this mast extension is made for heavy labor.

Whether you sail high-wind racing gear or you like to drop in on some huge waves, this mast extension will survive it all.

The fiber-reinforced nylon base is strong and reliable. Its combination with a carbon tube allows for keeping an overall extension weight low and gives a direct feel between your rig and the board.
