For over 50 years, the French tannery Haas has been crafting Arosa Calf, a leather known for its incredible quality, durability, and the way it develops a rich patina over time. Made from the finest French calf hides, it goes through a special double tanning process that deepens its color and gives it a smooth, velvety feel.

What makes Arosa Calf special is its perfect balance of strength and softness, along with a timeless character that only gets better with age. If you love the charm of leather that tells a story, this is for you. With use, it darkens slightly and picks up marks that reflect your daily adventures—a beautiful reminder of a life well lived.

This natural aging process is part of its appeal, giving it a well-worn elegance, much like a cherished old saddle. If you prefer leather that stays flawless, Arosa Calf might not be the right fit. But if you appreciate the warmth and personality that come with time, you’ll love the character it develops.
