You can choose to upgrade the leather of your apron to a Super-Soft chrome tanned Black Leather. This is a top grain, pebble finished cowhide leather that weighs 5 - 5 1/2 ounces. Chrome tanned Super-Soft leather is not prone to shrinking when exposed to high temperatures like Elk and other soft leathers are. When you need softness, flexibility and comfort, this chrome tanned leather delivers and then some!
