Giro Method Adult Snow Goggle - Camp Tan Cassette Strap with Vivid Smoke/Vivid Infrared Lenses

This product is listed as giro contact but when you select some of the different color options it looks like the giro method goggles. Which are they?

What is the sizing of these? It’s listed as part sun, full sun, large, and one-size. What does that even mean?

Does it come with extra lense? If so how do I know which extra lense color it comes with?
