Introducing the Clip and Go Agility Jump Bumps. This product is made of lightweight foam and covered with UV-resistant plastic coated vinyl (PVC), which makes cleaning a breeze. Each one weighs 2lb, and is 47" long, 8.5" wide, and 4" tall. These can used for a wide variety of jump exercises and drills (indoor or outdoor!), as well as teaching contact approach striding. The large package includes 2 bumps. However you can also select the bundle option which will change your order to 2 small, and 1 large bump for an additional $20.
