This is a Source Tactical Advance 3 liter hydration backpack that i tricked out to look cyber/post-apocalyptic. This has been decorated with marker, acrylic paint and dust with everything sealed with a clear coat to preserve it.

One of a kind, never used it! The mouth packaging is still on. Was going to wear it to Wasteland Weekend but never did- figured someone else might love it.
