What material is considered the best choice for jesses and Aylmeri bracelets?

Leather is considered the best choice for jesses and Aylmeri bracelets due to its durability, strength, and comfort for the bird. Leather is a natural material that provides a good grip, which is essential for the handler to have secure control over the bird while also being gentle on the falcon's skin. It can withstand wear and tear from outdoor environments, making it ideal for falconry.

Additionally, leather can be easily adjusted to fit various sizes, ensuring a snug and comfortable fit for different bird species. It also has the advantage of being breathable, which is important for the bird's welfare during active hunting or flying.

Other materials like synthetic fabric might not offer the same level of comfort or breathability, while canvas and vinyl may not provide the necessary flexibility or durability. These alternatives can wear out more quickly, posing a risk during active use. Therefore, leather remains the preferred choice among falconers for crafting jesses and Aylmeri bracelets.
