Have been using the E1 flip-up modular for about 1.5 years. Quietest, best built helmet i've ever owned. Have the Sena SMH-10 in it. Can hear the speakers into triple digits. Took a chance and shipped it to Europe unused, rode the Alps with it straight out of the box...no hot-spots or drama. Adjustable and removeable visor. Easy to open button on chin piece. Snap-in padding. The secret agent flip down tinted visor is super high quality, not shitty plastic. It's more like a new pair of expensive Maui-Jims. I have several helmets, but this is my go-to for the last year and a half. Buy this helmet if you have the $$. No ragerts.
Got it for $410 delivered in 2017 (year old graphic style).
