If I rip or tear my new Workwear on a nail or tool, is that covered under the warranty?

Unfortunately, no.  The limited Lifetime Warranty covers the seams and workmanship only.  We cannot replace under warranty due to an accidental tear on the jobsite however our Workwear would be infinitely more resistant to a cut or tear from occasional or inadvertent contact compared to other pants such as jeans or painter's pants.
