    GrüneStrasse designed the Shellback’s Tri-Fold Garment System to meet the specific utility of Bike-to-Work Commuters.  The Dual-Utility Hanger allows the commuter to take their work attire directly from the closet and clip it into the Shellback Garment Sleeve. Upon reaching your destination, the Garment Sleeve is easily unpacked and can be hung by its external hanger until the rider’s locker room transition is complete. To pack casual attire, simply remove the Garment Sleeve and stow your attire in the Garment Module where it will remain dry, folded, and crease-free.
