Can anyone tell me what the diff is between the Prophecy and Phenom Smith Turbo series goggles? I've been looking at the Phenom Turbo; however, I don't see the option for the Sensor Mirror lens on them like I do with the Prophecy. If no diff's then I can make a decision.

I will also add, the non-turbo fan series Phenom goggle lens also fit the same as the turbo fan series Phenom. I bought a bunch of the Smith Phenom lens and use them on my Phenom Turbo-fan. The only difference is the lens on the non-turbo fan have an added sliding vent at the top. I like it better then not having the sliding vent anyways... seems like an added bonus to me. I've been using the goggles and lens a lot for over 3 years now. Check them out here: http://www.backcountry.com/smith-phenom-replacement-goggle-lens There's a sensor there! Your choice. they fit though, and no performance is lost, performance improved in my opinion.

Smith Knowledge OTG Turbo Fan: Accommodates a wide range of eyeglass sizes, should fit all types of bulky glasses. Smith Prophecy Turbo Fan: Accommodate most eyeglasses without the added bulk of traditional OTG goggles. More of a tighter, close fit goggle for glasses. Smith Phenom Turbo Fan: For everyone that DO NOT wear glasses. I suggest you look around at buying a sensor lens, or wait for BackCountry.com to stock up on more Sensor versions, if your after the sensor, and assuming you don’t wear glasses under the goggles... The Phenom is the style you'd want to go for. Hope that helps :)
