This turtle-shell sponge knee pad features a thickened segmented foam protection structure with a 3D impact-absorbing design, helping to disperse external force and reduce pressure on the knee during movement. The soft and elastic fabric provides a comfortable fit with secure support, while the open-back knee design improves breathability and flexibility when bending. With moisture-wicking, shock-absorbing, and anti-impact performance, it is suitable for sports training, outdoor activities, cycling, skateboarding, roller skating, basketball, and everyday knee protection.
