【Supervised by a Practicing Physical Therapist × Ergonomic Design】 This product is supervised by a practicing physical therapist with extensive knowledge of human anatomy. Thorough research on the shape of the arm and wrist, muscle movements, and daily activities has led to the pursuit of a "natural fit" and "comfortable wear." The design distributes the load across the entire wrist, providing peace of mind for those who need to use it for extended periods, such as during rehabilitation, after fractures, or sprains. It is ambidextrous, unisex, and can be used regardless of body type. 【Significantly Reduces Shoulder and Neck Strain with a 3-Point Support Structure】 The structure supports the arm with a balanced 3-point system at the shoulder, elbow, and thumb. Compared to traditional arm slings, this design reduces strain on the shoulder and neck, making it less tiring even after prolonged use. The approximately 8.5cm thick shoulder pad disperses pressure. The thumb support prevents the arm from slipping and maintains a stable posture. 【Easy to Put On with One Hand! One-Touch Buckle】 The one-touch buckle allows for easy attachment and detachment with one hand. The belt is adjustable with a single touch, allowing for a perfect fit regardless of body size or clothing. The smooth operation, similar to a seatbelt, makes it comfortable for going out, visiting the hospital, and sleeping. 【Gentle on the Skin and Highly Breathable】 The inside uses soft gauze material, and the outside uses breathable mesh material. It is less prone to stuffiness and safe for those with sensitive skin. The design also focuses on lightweight construction, and elastic gauze is used on the elbow area. This arm sling can be used comfortably all year round.
