Hauling prey: The main function of the strap is to haul prey. It is usually made of tough and durable materials, such as nylon or polyester fiber, which can bear the weight of prey and the pulling force during hauling.

Adjustable length: In order to adapt to different sizes of prey and hauling needs, straps are usually designed with adjustable length. Through buckles, hooks or other connecting devices, the strap can be adjusted as needed to ensure that the prey is firmly fixed.
