CP only seems to call it "Napa" leather. Which is as descriptive as "red" is for wine. I've heard that it's "French calfskin," which is unconfirmed. Some suspect corrected grain. Personally I think it feels like calf-lined top grain. Definitely not full grain though, it's just not thick enough. Compare to 1ks or a Saddleback product to see the weight of full grain. But you wouldn't want lined, full grain sneakers. That would be too thick IMO.
