Familiarity: I've put it through the wringer
From the uncompromising field of view to the speedy lens change, the NFX2 is an amazing goggle. They look incredible, kind of like an old-school cylindrical goggle, but upgraded with a futuristic frameless aesthetic. They're a bit smaller than the original NFX, which is good if you don't prefer the Daft Punk-esque look on the mountain.
However, these fail miserably on deep powder days. This season has been absurdly deep in Utah, with many days seeing fresh powder with overhead face shots. The Swift Lock system is susceptible to incoming snow, should you get barreled with a hefty spray of powder. Some of the days I've had absolutely no problem with powder coming through, others I've had to remove the lens after every lap to wipe away the inside lens. Probably has to do with the snow's moisture content and the small space tolerance along the lens attachment/bottom seal.
If Dragon is listening, I'd recommend revising the bottom seal, so you don't have to worry about powder flying through. It's hard enough to see on those deep powder days, let alone with powder coating the inside lens of your goggles. Also, adding back the lens ventilation holes of the original NFX would help with condensation build-up on those soaking-wet days.
