A recycled classic One of our oldest products, the Bat Cage continues to offer simple, reliable performance, and it is now made from recycled fishing nets. Fishing nets account for an estimated 10% of plastic in the ocean and are 4x more damaging than other plastics. This design and use of recycled materials help keep unwanted waste out of our water. A global issue Each year 8 billion kilos of plastic enter the oceans, polluting beaches and waterways around the world.
