I've worn countless helmets, out of them all this is the only one worth mentioning as it totally changed my experience with helmets entirely.

Really worth the premium in my opinion; the vents are really phenomenal with air flow. Coolest helmet I've ever worn. Often times I even forget I have it on.
Plus if you're into a morbid looking helmet, you've found it; with some artistic talent you can easily make it look like a large maggot infested festering head wound. To be honest, at first glance, the whisper gave me chills as the holes really look like those by maggots but soon this fear turned into a morbid longing for one.
