I specifically bought this equipment so that I can wear the chest protector without the arm pads if I so choose, and for the removable chest piece to allow for my Bionic Neck Brace to fit more properly. My Bionic Neck Brace doesn't fit perfectly because even though the back plastic is recessed for a neck brace, my brace rides a little high in the back of the head area, yet the shoulder area of the neck brace still sits in contact with my trap muscle area; however, I still feel very comfortable with my neck brace on. I have ridden most of the summer with this equipment on twice a week at my local outdoor mx track. I was willing to accept the logical aspect that I will be warmer than the typically protected rider, and was able to ride confident and comfortably while remembering to stay fully hydrated. I'm very satisfied with the quality and comfort of this product, and feel that it will protect me better in the event of a crash.
