This piece is made of Aniline Dyed Leather. Only the best quality hides are reserved for this process, where the skin is tumbled in vats so the dye is completely absorbed by it. There is no other coloring agent or process, thus the finished leather tends to look and feel more "natural" - the unique markings and character of each skin are apparent. These gloves are waterproofed, and feature a rain wiper on thumbs, a gel palm pad and high performance insulated liner for extra warmth. Sizes X Small to 3X Large.
