Protects the Ninjaline if you choose to add a swing
Reduce the friction of the 2 pieces of material (swing and Ninjaline) rubbing against each other during use
The parallel movement of a competitor moving down the line, obstacle by obstacle, is what the Ninjaline was built for. These sleeves will help preserve your Ninjaline for many years of fun!
Be aware: We recommend that you take down your Ninjaline when not in use and store it in a dark place. This will extend the life of your line and is better for the overall health of your trees.
