We make this vest from real, thicker calf leather. The leather is 3.8 mm thick, which is lined with another layer of 1 mm thick lining. We equipped it with 2 cm wide straps on both sides, in the front, on the shoulders and in the back, which can of course be adjusted to be smaller or larger. There are 3 straps each in the front and back, 2 straps each on the sides and on the shoulders. We make it custom-made, please enter your chest circumference.
