Nylon exterior.Urethane interior.Lightweight and durable oxford nylon exterior.The nylon on the top and rim part are full of fine details to reduce weight, such as changing the thickness of the thread.The urethane used for the core material is thicker around the rim compared to the top for better balance and more stable flying.Also, this urethane isn’t absorbent so it floats in water.Also great for waterside leisure.The 9.3 inch (235 mm) diameter is just right for flying or catching.
