HELPS MAINTAIN NATURAL MOVEMENT & SHOULDER PAIN RELIEF: a unique design that guides and centers the arm in the socket so the shoulder maintains proper natural movement without impacting mobility. The support is easy to put on and take off thanks to its high elasticity, and it is secured to your upper body with a soft strap. SPECIAL ENGINEERED FABRIC: knitted fabric is soft, breathable and moisture-wicking. The Perfect Fit sizing system goes beyond small, medium and large for a comfortable fit that stays in place all day with the proper amount of compression. ENSURE CORRECT FIT AND SIZING: With your arm relaxed, measure the circumference of the bicep at the widest point. Make sure measure tape is not too tight or too loose. Refer to sizing chart & video for correct sizing. HELPS RELIEVE PAIN & DISCOMFORT: The full pain-relieving effect of the support is produced during movement. As you move, the support activates the muscles and gives an intermittent massage on the soft tissues. USED TO HELP TREAT & HELP PREVENT: shoulder arthritis, pain, instability, swelling, tendonitis and other shoulder stability issues. THE BAUERFEIND STANDARD OF QUALITY: All Bauerfeind products are made in Germany with the highest manufacturing standards to ensure superior quality. Bauerfeind technology has evolved over the past 80+ years and continues to set the standard in fit, comfort, support and performance. OmoTrain S provides secure support for the shoulder joint and strongly promotes mobility in order to restore function. During each movement, the compression knit and a removable massage pad with frictional nubs (Delta pad) massage the soft tissue, thereby relieving pain and activating the musculature that stabilizes the joint. Simply slip it on using the healthy arm, pull over the head and arm, and secure in place with the Velcro fastening. Thanks to its direct strap system, the support participates in every movement and is easy to put on and take off. It is therefore particularly suitable for use in pain therapy, for immediate care for injuries and for protection against further injuries both in everyday activities and in sport. It provides intermittent compression to the shoulder which increases circulation, relieves pain and swelling, improves joint perception and activates the joint-stabilizing muscles. Made in Germany with the highest quality standards. Bauerfeind is the brand chosen by top professional and Olympic athletes.
