Leather weight??

[fedoralover]

Pardon my ignorance jacket buffs, but I've seen different leather jackets advertised as being a certain weight, ie. 3oz, 3.5oz etc. What is this applied to, per square foot of material, or what??

It is the thickness of the leather. Each ounce of thickness is roughly equal to 1/64 of an inch of thickness. So 3.0 to 3.5oz is like the thickness of a penny. I googled it!
