The Standard Issue 13 was the first project I ever made as a leathercrafter. It took 10 years to perfect it and now it can be yours. 
 
Watch how we make the SI13
 
I wanted to give you the option to outfit the bag to fit your needs. The stock SI13 comes with one single compartment on the inside but you can add just about anything. Simply choose your leather and hardware options and then use these links to outfit the bag with up to 8 options. Simply add them to the cart after adding the bag.
