The testing program wanted me to comment on the "warmth" of the product. I have no idea what that even means. A good product that is easy to apply and forms a good water-repellent protective layer on the skin. In this case my new combat boots. They are good for all skin types, especially in dry climates, which is what these boots are for. It protects the skin from drying out and cracking. There were no instructions which isn't a big deal but I thought I'd mention it. There is probably a 'preferred' way of using it and I think the manufacturer should be responsible for communicating that to consumers.
