Saddle Sponge
 
An easy way to cool your horse down on endurance rides or just long trail rides at home.
Simple steps to follow:
Squeeze the sponge and release it in a bucket of water, and allow the sponge to soak in the water
And simply thread the rope into the saddle loops and put the sponge through the loop of the rope, and pull to secure
And during your ride, wipe your horse down and at a checkpoint, resoak with fresh water
