About this item【Lightweight】The Arm Sling (size medium) weighs less than quarter of a pound, which is equivalent to the weight of two eggs. The arm holder is made of sponge material with air holes, making it lightweight, soft, ventilated, and breathable. It absorbs sweat quickly, providing a comfortable experience akin to being wrapped in a blanket, without feeling stuffy. You’ll unconsciously forget it’s even there. This sling is ideal for sleeping but can also be used at home, during trips, and at work. 【T-belt Design】This Shoulder Sling features an innovative T-shaped strap that wraps around the waist, securely holding the arm close to the body and preventing swinging, effectively stabilizing the shoulder. Moreover, the sling is free of neoprene and latex, ensuring there is no odor or skin irritation. With exquisite workmanship and a low-profile look, this sling is both sturdy and durable. Available in various sizes, it is suitable for men, women, teenagers, middle-aged, and elderly people. 【Sponge Strap without Strangling Neck】The shoulder strap is filled with a soft sponge, ensuring a lightweight and comfortable experience even during extended wear. It eliminates the risk of strangling the neck, maintaining proper blood circulation, and effectively reducing pressure on the shoulders and neck. This support will not only provide relief but also offer comfort during your recovery. 【Comfortable to Wear】Experience comfort and ease with this Shoulder Immobilizer Sling. It provides perfect fixation and protection for injury nursing, including shoulder muscle and tendon pain, shoulder joint instability, dislocation, sprain, contusion, rotator cuff surgery, acromioclavicular joint injury, and more.
