I purchased the dual layer fog resistant irid faceshield for my GP3 carbon directly from Bell, it looked awesome but broke almost immediately at the hinge points. It's super brittle and certainly not worth the $149 I paid for it. I have a K1 pro with single layer faceshield that has survived an entire season of hot laps and about half a season of racing. The SEO3 only lasted 2 races. I'm really dissapointed!
