The Medisana GP105 reusable gel pack Hot & Cold Pack is a flexible cold and heat pack designed for targeted relief of pain, swelling, bruises, or muscle cramps. It is specifically designed for use on larger body areas such as the leg or knee and offers a comfortable and even coverage thanks to its flexible material. The hot and cold application relieves pain, swelling, bruises, and muscle discomfort. Ultra-soft, flexible material with 360° coverage ensures a comfortable fit on the leg or knee. The pack is reusable and durable for regular use in everyday life or sports. For cold application, it should be placed in the freezer (at least 2 hours), and for heat application, in the microwave (approximately 45 seconds at 800 W). It is suitable for the thigh and calf areas with a defined circumference range of 29 to 42 cm. The pack remains flexible even in a frozen state down to –18 °C, thereby comfortably adapting to the body's contours. It is designed for applications of up to 15 minutes and is made of easy-care, non-toxic material with a durability of up to five years. This makes it a practical, easy-to-use aid for household, everyday life, and sports injuries.
