I use the one given to me...i never upgraded to the non newbie one (from yellow to white for my company) because people leave me alone. I mechanic i dont know what the fuck they are doing...digging a hole? sure
As for safety, they leave me alone. i do my job as safely as possible and the unsafe shit cant be made safe. only thing ive ever heard anything about has been hi-vis. I dont have it on when im using a torch or welding because its polyester hell
