The bag is really spacious. I have placed a 26 'hose in the outer carton, a Co2 pump with 2 additional cartridges, 3 Piece Cable lifter, 2 piece pant leg brace and a repair kit box. And I have the zip to expand the storage space does not even have to use. Accessing the motto. Can easily accommodate the saddle and remove by quick release at any time without further ado. Let's see what happens when it rains? But it looks quite water resistant.
