I had the EXO 400 before my RF-1000. They both fit totaly different. The Shoei was more of a "scratchy" feeling, for lack of a better term. It wasn't scratchy, but the Scorpion has that sweat absorbing inner and it feels good. But the physical fit, the way it goes around your head, is a lot different. But the Shoei's vents work AWESOME! But the Scorpion comes stock with the anti-fog shield that works awesome too.
