Details from Dragon:
The latest in our premium offering, the PXV2 goggle is the distillation of years of goggle design. We took our groundbreaking Panotech design and fused it with the utility and ease of our Swiftlock lens changing technology. It's sized in the sweet spot: slightly smaller than the PXV and larger than the best-selling NFX2. And of course, the PXV2 utilizes our best-in-class Lumalens color optimized lenses and armored venting. This goggle utilizes features derived from Dragon's patented Advanced Projects X (APX) technology.
