Airflex is extremely breathable material for cool comfort during active use. It is specifically designed for air circulation, heat transfer and moisture wicking away from the body. Any activity where excess heat or perspiration could be felt under the brace is an ideal application for this product. Additionally, it is stretchy and smooth for the highest level of comfort. The Ortho Active Airflex Thumb Lacer immobilizes the thumb with a pre-formed, moldable, aluminum stay. This comfortable support stabilizes the CMC and MCP joints. It is easily applied using our popular lacing closure system and is adjustable for each individual with a Velcro closure over the thumb.
