The third normal reusable gel pack is with fabric material pouch.
There are several fabrics for customer’s reference, such as polyester, flush fabric, knitted fabric and so on. This is most comfortable gel pack and it is top grade. Also the function is the same. The gel pack is no need with any other wrap together. We can use it directly onto skin. The fabric gel pack can be put in microwave oven for heating and freezer for cooling.
