Were the high tractions even out last year? I thought that was new to this season, but I also did not need new skins last year.
I honestly don't know who makes the K2 skins, but it is not G3. The plush is different. It is more akin to Ascension skins, but pretty sure it is not BD either. As far as performance goes, I don't know. They look well made enough that I suspect they are just fine. You might try pming KyleMiller. He's a K2 athlete and all he rides is the Panoramic for over the last year or so. Plenty of experience with their skins with that guy.
