I never worn a cage before...wear a visor. Thinking about getting a cage with my new helmet. I've heard chrome cages are probably best for visibility. So I've limited down to the chrome, or the Itech two-color cages. Any suggestions in terms of model? And what about sizing. Never worn one, and it's a pain to get to the shop. What size would I be looking at...I wear a medium helmet and supposedly you measure from eyebrow to chin and that's 7" for me. And how exactly do you wear it? I've seen guys with the cage up in the j-clips and barely touching the chin cup while I've also seen guys with the chin in the cup actually and cage is being help there by the straps only.
