Material The outer skin of the Fitness Sandbag is crafted from space leather. It resists friction and damage, offering durability and easy cleaning. The surface protects floors and your hands during use. Ergonomic Handle A widened webbing design provides a secure, tight grip. This reduces palm strain and improves comfort, while the handle is designed to stay in place during wide grips to help prevent slipping. No Sand Leakage The sealing is hand sewn for durability, with a secure closure that prevents sand or cotton leakage. This design greatly extends the life of the sandbag.
