Think of how hard it is to film one full video part. Okay... now think about how hard it must be to film over a dozen full video parts. Koston has always been ahead of the pack, and watching all of his video parts proves it time and time again. The parts he filmed in the early 90s could be released in the current day - they're still that good. So, to honor the 40th birthday of one of the greatest skaters of all time, we've compiled all of Eric's full parts from the past 25 years. Wow, just think about that for a minute — 25 years of full parts... holy shit. Do yourself a favor and get lost in the vortex.
