Brand new insulated nylon saddle bags that fit over your saddle horn. A must for trail riding. Very convenient for carrying your cell phone, first aid kit, lunch, drinks, and snacks on long rides. There is a bag that measures 9" across, 10" from top to bottom and about 3 1/2" from front to back that you can keep papers, cell phone, snacks or whatever. There is a smaller pocket on the side too that you can put keys or coggins papers in it. The other side has two water bottles. I generally freeze one so that when I am finished with the first one the other one is ready to drink. Heavy nylon construction with zipper closures to keep things from accidentally falling out. Built to last!
