SurfTech SUP Paddle Guard Kit protects the edges of your paddle blade to increase its lifespan. It will also protect the rails of your board, not to mention your ankles, from paddle dings. It will not affect your paddle's performance. Easy to apply, comes with full instructions.
I purchased the Surftech paddle guard for my wife's new AXE carbon fiber paddle. We're both new to SUP and hit our boards from time to time, I felt this and railsaver tape would protect both our boards and paddles. I was impressed with the instructions and the relative ease of installation. It does what it's advertise to do plus protects your board's rails as well.
The stuff is easy to install, protects the paddle and boat/board and doesn't seem to hurt performance. So I only have one question, why don't paddles come with this installed in the first place???
