We developed this bag from customer requests. We created the main body from a single piece of leather. The zip closure has a narrow lip of leather on the inside bottom edge which means the exposed zip doesn’t not allow water into the bag and damage the contents. The bag has been “road tested” in the Kenyan highlands and endured torrential rain with a 100% dry interior. It has an internal pocket for extra security of specific items such as driving license or smartphone. This particular design incorporates a sleeve to slip through the belt of the wearer and a buckled strap to secure the bag to the wearer’s leg. Ideal for touring allowing easy access to documents, cash or phone. It also makes for a good emergency tool kit holder!
