This is the RS Taichi TRV037 SEPARATE HONEYCOMB CHEST PROTECTOR, a separate chest protector. I purchased it in 2015 and wore it once or twice a year when riding on the circuit. This year, I bought a new protector when I updated my riding gear, so I'm selling this one since I no longer have a use for it. There are no noticeable stains or scratches, but please understand that it is not new.
