- Size Chart: Please refer to the size chart in the listed images to order the right size. Measure your waist with an elastic tape measure and do not rely on pant size. - Comfortable and light: Neoprene construction and mesh upper provide comfort and breathability. The interior is lined with suede material for a skin-friendly, body-hugging feel. - Locking closure: Uses a high-quality roller buckle system. Steel ring buckle for firm stability, with a ring buckle upgrade featuring a self-locking bar and double reinforcement. Auto-lock design helps secure your waist and improve performance. - Perfect fit: The wavy shape and conical design deliver strong support bars to stabilize the torso. Five support bars relieve the lower back. The U-shaped design adapts to the lower back, is ergonomic, and supports strength. Narrower side areas enhance comfort and freedom of movement during any workout. - Use scenarios: For squats and deadlifts to stabilize the core and protect the back. For overhead presses and heavy lifts to maintain a solid core brace. For dynamic training or cross-training where movement is varied but torso support is needed.
