Sensi Tec construction is the material used for Product 1, which has a circumference of 26 inches and weighs 9.5 ounces. The bladder of this product is made of butyl.

In contrast, Product 2 features a Cordley composite cover and is of regulation size. This product was the official ball of the 2000 USA Junior National Volleyball Championships and also has a circumference of 26 inches.

The construction and materials used in these two products differ, with Product 1 utilizing Sensi Tec and a butyl bladder, while Product 2 is made with a Cordley composite cover. Both products, however, share the same circumference of 26 inches.

While Product 1 has a weight of 9.5 ounces, the weight specification is not provided for Product 2. The key distinguishing feature between the two products is the cover material, with Product 1 using Sensi Tec and Product 2 employing a Cordley composite.

Furthermore, Product 2 holds the distinction of being the official ball used in the 2000 USA Junior National Volleyball Championships, indicating its suitability and approval for competitive play at that level.

In summary, the two products, while sharing some similarities in terms of size, differ in their construction materials and, in the case of Product 2, its official status for a specific volleyball championship event.
