Loggers and tree pruners are distinguished by the equipment they wear, and in particular their trousers . These trousers play a crucial role in protecting these forest workers. The durability of these trousers is ensured by the use of resistant and elastic materials such as polyester , nylon , and cotton canvas . These fabrics offer effective protection against forest obstacles, from branches to thorns. Functionality and practicality are also emphasized. Stretch panels and adjustable waistbands allow for freedom of movement , facilitating daily work in sometimes difficult conditions. Multifunctional pockets and tool holders add a practical dimension, allowing easy access to essential tools. Finally, safety is not neglected; to minimize injuries, some trousers feature knee reinforcements. Certain models even incorporate reflective strips for better visibility.
