Why do I so adamant about getting these?

My DAD. [Linked Image]

He told me that about 90% of jobsites and coal mines won't let you on site without them.

So, Do I need them?

I just never questioned his comment, I figured he knew ( though he's not in construction).

I'll check-out Redwing.

Thanks much fella's!!!
