Interesting concept, weirdly executed
This consists of a molded foam elbow-shaped support in a stretchy fabric.  The foam support is very comfortable.  However, the fabric is awful.  Stretched over your arm, it feels scratchy and retains heat.  It is also easily snagged.  What I did was cut the foam out of the fabric (two snips) and put it inside a large stretchy comfy terry cloth sock and cut off the end so I could slip it over my arm.  Improved it a million percent!  So, if you want to spend a little time modifying it, this will work well for  you.
