The ULTRASLING PRO is a brace for immobilizing the shoulder joint... an arm sling. (Does not put pressure on the neck) - Model Name: DonJoY ULTRASLING PRO - Color: Black - Size: Free Size - Universal for left or right shoulder (currently set up for left shoulder) - Unisex (used by a 176cm tall male) I used it for about a month after rotator cuff repair surgery. It looks bulky, but I didn't mind it while sleeping, and I was able to successfully stop using it. Velcro is used in many places, and there is some lint, so there is a slight feeling of use. The purchase price was about 23,000 yen. Thank you.
