A padded mini-gear bag, the BlocBox is large enough to hold your shoes, chalk bag and personal items. Its taco-style design and zipper closure seals everything in securely. Unfold it for a sit-start pad or a dry place to clean your shoes, and when your session is over, zip it up and slide it inside a Drop Zone or Mondo crash pad. Its small zippered pocket is accessible even when it's wedged in a larger pad.
