Thank you very much for viewing this product from among many others. This is a Bagjack messenger bag, a special order from Bishop. I purchased it about 4 years ago and used it as my main bag for about 2 years, but I haven't been using it recently, so I've decided to put it up for sale. While there is a general feeling of use, there are no tears, and it can still be used. I've used several messenger bags, but this one was by far the easiest to use. ＜Design＞ - Messenger bag made of Cordura nylon - Special order specification with a silver Cobra buckle for the front clasp - Removable inner bag for washing when dirty - L-shaped shoulder strap that fits the body - Equipped with a unique system called quick release for easy adjustment of the strap length - External zipper pocket with Velcro for adjusting the gusset - Detachable inner pocket with a zipper - Attachment point for bicycle lights - The opening prevents rain from entering with a drawcord closure and flap ＜Material＞ - Durable Cordura nylon is used - The inner bag is made of tarpaulin, which is durable and waterproof, also used for tents Size Approximately 15cm wide x 40cm long x 30cm high.
