What is “normal wear and tear”?
“Normal wear and tear” includes but is not limited to: scaling a cliff face, downhill mountain biking or skiing, parachuting, hiking rugged terrain, dropping your Numas on a hard surface, accidentally stepping or sitting on them, and even letting your toddler play with them.
