Review on Conquer SA2020 Approved Racing Helmet Interior Accessories by Enrique Espinoza

I ordered large first and it turned out to be so tight that after 3 minutes of wearing it I got a headache. Then I googled helmet customization and found a video showing the Conquest helmets. Their opinion was that their size is a bit smaller than other manufacturers and if you usually order this go up a size. I should have checked it out first but just ordered what came with all my other helmets - Bell and others - in a large size. XL fits like my previous large helmets. Otherwise the band works perfectly, the fit and workmanship seem to be fine. Haven't worn it to a track yet. (Clarity (what the heck is that?) or "thickness" I didn't rate. How do I tell how thick it should be. Years old Would order again .in XL.
