Utility kilts for grungy mechanic work

[kingandrew]

You may also want to look into leather kilts, for the same sorts of reasons that many metalworkers use leather aprons.

Leather isn't machine washable, but it would hold up to plenty of abuse, shed a lot of dirt and gunk that stains cloth, and provide some degree of protection against heat and sharp edges.

I have no experience with any utility or leather kilts myself. I know that blacksmith and other workshop environments were the inspiration for the traditional German lederhosen. Lederhosen might also meet many of your practical concerns, although they are not as "free-fitting" as kilts.

Best of luck in your search.
