This backpack is Bradley Mountains proudest creation. Each bag is handmade by their team in San Diego, and has been put through a tremendous amount of care and testing. All materials for this bag (and all of our products) have been sourced in the US. This bag was first designed as a one-off travel bag which Tyler took to Switzerland and Italy. This bag served as his only piece of luggage. After seeing how well it held up we decided to add it to our line.
