Kangaroo leather is especially durable for making cords and other products due to its unique structure and natural properties:

1. Compact and interwoven fibers: Kangaroo leather has finer and more densely interwoven collagen fibers compared to other types of leather. This provides greater tensile strength and durability without increasing thickness.

2. Lightweight: Despite being very strong, kangaroo leather is lightweight. This makes it ideal for products that require a balance between strength and flexibility, such as cords.

3. Flexibility and elasticity: It is more flexible than other types of leather, allowing it to bend and stretch repeatedly without breaking or deforming easily.

4. High tear resistance: Thanks to its unique structure, it is less likely to tear even under pressure or continuous wear.

5. Durability: Products made from kangaroo leather tend to last a long time, as they resist weather conditions, stretching, and abrasion well.

These characteristics make kangaroo leather one of the preferred materials for making cords, specialized footwear (like soccer cleats), and other high-quality products.
