Mr. Fusion Frame Bag
Porcelain Rocket Mr. Fusion Frame Bag Review
Tested and reviewed for bikepacking use
Porcelain Rocket builds the Mr. Fusion custom in their Edmonton workshop, and the attention to detail is immediately apparent. The VX42 X-Pac fabric is stiff enough to hold its shape yet light, and every bag includes a removable internal sleeve for organizing smaller items. The taped seams and waterproof zippers keep everything dry.
