The ProFlex 655 Neoprene Compression Arm Sleeve with Strap provides comfortable elbow and joint support on and off the worksite. The stretchable perforated neoprene stretch fabric compresses the elbow to improve blood flow, injury recovery and joint flexibility. This compression elbow sleeve is a great solution for reducing pain and increasing productivity. This comfortable latex-free arm sleeve is made with a breathable perforated neoprene that does not limit range of motion. Soft spandex mesh in the elbow crease further enhances airflow for all-day wear. A secure hook and loop strap around the forearm allows the wearer to adjust to desired support level and fit, while the contoured ambidextrous design allows for wear on either arm. The low-profile style easily fits underneath clothing, but also can be worn on top depending on preference. To determine size, measure the circumference around the center of your elbow while the elbow is extended.
