What's the difference between cold-proof cloth and non-woven cloth?

Cold-proof cloth is just a product name, and it is generally made of Tian Li Jinpin.

There are several kinds of cold-proof fabrics on the market, one is non-woven fabric, the other is cloth and plastic film.

But it's good to use non-woven materials.

This cloth is too heavy and expensive.

Plastic film, airtight, will burn the heel.
