The CMC-X" Lacer Thumb Stabilizer helps provide pain relief from carpometacarpal (CMC) joint arthritis while permitting you to do the activities you enjoy.  The CMC-X Lacer has the same X straps and stay pod as the original CMC-X" Thumb Stabilizer.  However, the CMC-X Lacer has a speed lacer closure system around the wrist for faster application and is bilateral so a given size will fit both the left or right thumb.  The body of the CMC-X Lacer is made from hypoallergenic CoolFlex^" material for comfort and compression.  The CMC-X Lacer does not contain any natural latex rubber or neoprene.
