Of Course! The sleeve is interchangeable as long as the size is right. You can wear the FREEZE SLEEVE on multiple body parts including your elbow, forearm, calf, bicep, quad, wrist, ankle, knee or any other part that your sleeve can slip on to. Be sure and check your measurements to ensure proper fit for each area! (To size an area like your calf, measure the diameter of the widest part.)
Most people will not use the same size for all body parts. You will need a larger size for your knee than you need for your elbow. Make sure you have the right sizes for the areas you are applying compression cold therapy to.
Other treatment areas that are in development include the shoulder and back sleeves.
