How essential is it to be riding with a hard back protector? In all my years with a class 6 I've never owned or ridden with one (never even tried one on actually). I've just depended upon the foamy things that come standard with my jackets or leathers.
Are you supposed to ditch the foamies and replace them with a hard shell asap? Do you size your gear to ensure your have enough room to wear a hardshell underneath? I regularly ride with a backpack so would they interfere with each other?
I commute about 60km per day on my bike so maybe a hard protector is a good idea for me unless they're really just meant for racing or spirited riding.
Any insight is appreciated!
