Designed to fit either the left or right arm, these Sling and Swathe Immobilizers provide comfort and security during rehabilitation. They are made with soft pile foam that is comfortable against the skin. Two over the shoulder straps criss-cross and attach with contact closures for an accurate fit. The immobilizer may be used as an arm sling if swathe is not desired. Choose between Large/X-Large and Medium/Small sizes.
