Smith I/O comes with ignitor (35% VLT) (all conditons rose copper base w/ flash mirror) and Sensor Mirror (70% VTL) best low light lens on the market by far. Have skied with the hiViz yellow from Oakley and was not impressed. Plus smith goggles are shperical and optically correct to prevent distortion. The gasket that they use on their double lens is also much stronger than any one elses, and their porex filter blocks out moisture while stil allowing airflow between the lensens, where other companies lenses have foam gaskets to allow for airflow that can break fairly easily and allow moisture in everytime u ski after that.
this, i believe they also make the turbo fan for the prodigy which fits larger than the phenom if you have a big noggin
Agreed, I love my EG's to death, but when hiking or on those really deep deep pow days, they tend to start to fog.
I also have Crowbars, started with a pink iridium lens and to be honest, was not a fan at all. I traded it for a Hi-yellow and loved that lens for the overcast/powder days. I got a Hi-persimmon one this off-season, gonna give er a go.
