What is the main advantage of the Aylmeri jess over the traditional jess?

The Aylmeri jess is designed with a removable swivel strap, which is a significant advantage over traditional jesses. This feature allows for easier attachment and detachment of the jess from the bird, providing flexibility in managing the equipment. The removable swivel also helps reduce certain types of wear and tear that can occur with traditional fixed jesses, where the connection point might become worn over time.

This adaptability is particularly useful for falconers, as it can facilitate quick adjustments during training or hunting situations without the need to completely replace the jess itself. The ability to remove or replace the swivel strap enhances functionality in a way that traditional jesses do not offer.
