Rogleather

Considered one of the top leathers in the industry due to it's particularly sturdy nature, Rogleather is not only strong enough to cope with severe changes in climate without cracking, but also has the capability to repel piercing attacks, including those of the magical variety.

Because of it's exceptionally protective exterior, even the most skilled of leatherworkers have difficulty working with this rigid material, and will often dispose of dozens of needles when producing a single article of clothing.
