The two fixing base layers 4 are respectively adhered to the upper and lower parts of the cold-resistant layer. A silver fiber layer is also provided between the rare earth intermediate layer 3 and the fixing base layers 4. Specifically, the elastic mesh support layer 2 is woven from elastic yarn. By setting the rare earth inner layer 1 and the rare earth intermediate layer 3, the cold-resistant effect is increased by utilizing the characteristics of rare earth fibers. Moreover, setting only two layers is thinner than pure cotton after multiple layers are stacked, achieving a thinner and better cold-resistant effect.
