Made from "Vintage Horse Light" horsehide with a thickness of approximately 1.0 mm. Compared to heavier leather qualities, the material is noticeably more flexible and more comfortable to wear from the start, without losing the typical character of horsehide. The surface and feel are inspired by historical examples and will develop a visible patina over time.
