Light compression from this wrist and thumb splint helps reduce thumb and wrist pain associated with arthritis, tendinitis or repetitive motion.  This hand splint is made of a lightweight, perforated 1/16 in neoprene with a soft, terry cloth liner that helps keep skin cool and comfortable.  The Comfort Cool Arthritis Wrist and Thumb Splint has added length to fully support both the wrist and thumb. The hand splint features a specical pull-through wrist strap that requires less hand manipulation to adjust and fasten the splint.  Hand wash and air dry.  To size, measure the palm circumference.
