Chulksmack: This year, Brad Kremer finds a new home at Mack Dawg Productions, bringing his trademark manic energy, humor, and flawless eye for shooting snowboarding action to Chulksmack. As you’d expect, Mack Dawg once again ‘ups the ante’ with some of this season’s burliest jumps, jibbing, street rails, and awe-inspiring tricks from the world’s top athletes. Chulksmack, a 17mm snowboard film. One millimeter better.
