Trigun Backpacks are backpacks with a twist! They don’t just come in any old color, you can design your own. Trigun is a popular anime series with its own shop and range of in-world products. There are all different types of Trigun backpacks available, from ones that look like the bag used to hold Trigun’s signature weapon, the Vashta Nerada (the B.A.F.), to ones that have character designs on them.
