4000 Black BC NW Aeropac Tail Trunk

Our Chase Harper USA 4000 Aeropac Tail Trunk Bag is another great addition to the Aeropac line. It is a very spacious bag on its own with close to 20 Liters of storage but was also designed to complement any Chase Harper USA saddlebag set without any fitment issues. Constructed from Industrial Grade Urethane Coated Ballistic Nylon with double stitch sewing and using a lightweight yet very strong thermoplastic insert, the 4000 is rugged and will maintain its aerodynamic shape even when its empty. The non-abrasive vinyl on both the bottom will prevent damage and helps hold the bag firmly in place. The bottom also features a hideaway zipper compartment for the adjustable bungee mounting system which allows for this bag to fit onto a wide variety of bikes. Internal features include a key fob hook and full-length mesh pocket with hook and loop opening.
