Alpine is AGL’s premium clear plastic, and it isn’t made in-house. AGL’s discs come out of Innova’s factory, and Alpine is built on a Champion regrind, so what you’re holding is Champion-class material under a different name.
That puts it in the durable, glassy end of the range. It shrugs off trees, keeps its flight for a long time, and stiffens in the cold the way clear plastics do. Grip is the trade: dry it’s fine, wet it’s the slickest thing in the AGL line.
If you want the AGL feel with more hand, Polar is the same idea on a Star base. Alpine is the one you buy to keep a mould’s flight, not to change it.
