Hunting is a physical activity that can wear down the clothes in many ways. The quality is crucial to the expected life span of the jacket. Different fabrics tackle thorny bushes very differently.
However, the strength and abrasion resistance of the outer material does not determine the jacket's durability alone. Seams, buttons, zippers, membranes, and other detail can also fail, making the jacket less useful. A detail as simple as the jacket's washability when it becomes dirty (and it will become dirty if used for the intended purpose) is vital to the jacket's functionality over time.
