ArgyleNJSo I just ordered Spy Marauders and they came last week. I returned them immediately, but my taste is probably more of the exception to the rule. I haven't used goggles since I was a kid, I always hated how they fogged up so switched to sunglasses for the last 15 years or so. But goggles are clearly better when it's really cold.
Even when I wore goggles I never once thought about wanting a different lens, nor have I ever seen anybody ever swap lenses? Doesn't seem like something I need to concern myself with, but I'm also not skiing 50 days a year like I'm sure a lot of people here do.
If it is snowing really hard or just low light, it is nice to be able to put in the low light lens. It helps with shadows and just seeing in general. Some goggles it feels like you are going to break the lens or goggles, so it is nice when companies make it easy.
