The type of leather used in a jacket can have an impact on its protective capabilities. Different types of leather offer different levels of abrasion resistance, water resistance, and insulation.

For example, cowhide leather is more durable and resistant to abrasion than sheepskin or lambskin leather. It’s also naturally water-resistant and provides great insulation for cold weather. On the other hand, lambskin leather is softer but less durable and not as water-resistant as cowhide.
