The Game Ready® Full Leg Boot Sleeve with ATX has active compression that delivers cold therapy which works faster, penetrates deeper and lasts longer than other treatment modalities. The anatomic, low-profile design allows for more surface contact for a more effective cold therapy treatment. Each size adjustable for optimal fit, with easy-on/easy-off hook-and-loop closures for convenient application. The length of the Medium size can adjust from 30 inches up to 32 inches. Game Ready?s dual-action ATX Wraps (Active Temperature Exchange) features two separate internal chambers. One for air and another for water circulation. The patented design enables the simultaneous delivery of adjustable compression and continuous cold or heat therapy throughout treatment. This sleeve can be used with the GRPro 2.1 or the Med4 Elite™ Control Unit.
