"Ha, you think we wear these suits as a fashion statement?! Tell me boy, have you ever been down into the Sumps? The lights don't work right down there you know. Some days it's just you, your shoulder lamps, and kilometers of tunnel, flooded with Emperor knows what sort of toxic sludge. A hundred cycles or so ago I was down there and we had ourselves a little hivequake. Collapsed the floor beneath my feet and I went under. Sergey found me a few hours later. My legs were crushed under a girder, my lamp had broken and I'd long since screamed myself hoarse. The hi-vis flash of my suit in the dark caught his eye. And saved my life. So you can keep your fancy vest and your polished boots. This thing may be uglier than a grox-hide coat, but I wouldn't trade it for the world."
