I've never thought of this before but how does thread do on those things? Forgive my ignorance, I don't even know if firefighters wear the radio into fires. I'd figure that thread would be one of the first things to go all melty in a fire. Is there nomex thread? How does a comms system hold up in a fire? Sorry, I'd never thought of designing any leather thing for such a ridiculously harsh environment before.
Great looking stap, btw!
