The Schiek Downward Angle Design: Schieks unique downward angle design naturally follows the contour of your back for optimal support and comfort. This shape ensures the belt stays in place during lifts without riding up. Unique Schiek Tapered Hip & Rib Contour: Features Schieks signature hip and rib contour for a custom fit, eliminating pinching or discomfort while allowing for greater mobility during squats, deadlifts, and presses. Reinforced Neoprene-Coated Nylon: Added layer of neoprene-coated nylon makes this belt stiffer than the Model 2004, providing superior rigidity and durability for maximum support. Signature Schiek One-Way Velcro Closure: Schieks original one-way Velcro system ensures a secure and exact fit every time, with no in-between sizing. Dual Support Panels: Designed with dual-reinforced support panels to enhance back stability and reduce stress on the spine.
