These are great goggles for non-heavy snow days...not because of the lens' vision properties, but because the way it attaches. The four points of contact for the lens is intended to make it easy to interchange lenses when conditions change. However, in the BC when your life depends on your ability to see, you may want to consider the fact that after ice accumulated inside the lens, I tried to clean the inside with the cover but the lens continually popped out because it's not designed to be pressed on from the inside. I had to huddle down and put the goggles' lens inside my shirt for a bit before I could even bail. It did ruin my day. It really does have poor venting and the lens comes off too easily with routine handling. My model was 2009.
The positives are it works great when it's not pounding snow and fits my poc helmets perfect. I switched to the other cylindrical POC goggles and am happy.
UPDATE: I changed my mind, just bought another pair of lobes for blue sky days. Goggles are sick.
