The Challenge Saddle Bag is a leather tool bag for fitment to the rear of a saddle bearing bag loops. It features buckles that, whilst fastening the bag to the saddle, are located within the hold itself, thus ensuring greater levels of security. The strap that secures the unit encircles the tools it carries to prevent them from rattling during transit. Made in Italy from vegetable tanned leather, the first Challenge was designed and patented in 1896.
