FLA Safe-T-Sport® Neoprene Shoulder Support stabilizes and protects the shoulder to prevent re-injury but also allow flexibility. Neoprene material retains the body's natural heat for therapeutic and soothing warmth. The sports neoprene material in this shoulder support has a soft lining that surrounds the shoulder providing comfortable compression, comfortable four-way stretch for proper fit, and therapeutic warmth to the shoulder joints and surrounding muscles. A built-in pocket holds a reusable hot/cold gel pack (sold separately) in place over the tender joint. Chest and arm closures are adjustable, allowing for a custom fit. It fits either Right or Left and is easy to wear under clothing.
