The "UNION" series of backpacks features a distinctive form inspired by workwear and tool belts, with multiple functional pockets on the exterior. The main material is polyester canvas, which is lighter than cotton and less prone to fading. The characteristic front pockets, inspired by workwear and tool belts, are accented with rivets and eye-catching green name tags (navy has tags of the same color as the main body). All models except the flap backpack (08692) are equipped with two long handles for easy carrying, offering high functionality and a design that can withstand heavy use.
