Thermoskin Thermal Knee Support provides protection and support for arthritic pain and general wear and tear, including sprains, strains, and weakened knees. It promotes blood flow for enhanced recovery, is breathable and moisture-wicking, and provides compression and support. The seamless design behind the knee and elasticised edging help to minimise the migration of the support. The X-Large size fits a knee circumference of 44.5-49.5 cm. To use, slip the end of the support over your foot and slide it up and over your knee so that the middle section of the sleeve sits directly over the patella (knee cap). Always read and follow the directions for use. Do not wear within the first 72 hours following an acute injury. This product contains a synthetic fibre, which may cause allergic reactions. If an irritation or rash develops, discontinue use and seek medical advice. If pain persists, discontinue use and consult a doctor.
