well theyre very good at helmets and are arguably world leaders in that product. so why risk reputation and profits by expanding into different fields that they might not be so good at when they are doing just fine as they are.
I doubt expanding into other products will damage the reputation, C&D do bats pads gloves etc and they're still regarded as a good company imo
very true but if their protective equipment is poor then people might start doubting the company. if you get a bad product you tend to stay away from that company full stop whether it be the same good or something different! just my opinion but im no marketing expert.
