Cordova Safety Products grades leather according to the area on the hide from which it is cut. The premium-grade leather comes from the side or shoulder and from areas higher on the animal that receive the least amount of movement and is more durable due to the density of fibers. This glove is constructed of a premium grain, Thinsulate®-lined pigskin. Thinsulate is the warmest thin liner on the market. Because it offers the greatest breathability due to large pores in the hide, pigskin is ideal for wet applications, given its tendency to remain soft after exposure to moisture. This pigskin glove also provides an orange, hi-vis back, lime reflective knuckle strap, and extended knit wrist.
