All eva foam, foam dowels, and foam clay. As soon as I saw this piece and the tacticool/wastelandish armor with it I just knew I had to build it. This was the first piece I started on this build and the first fully painted, which proved to be a challenge considering the multiple layers. I used the halo ce legendary trophy skull templates from the 405th and Rakshasa armor templates from Etsy. Biofoam canister, underpad and tubes all freehanded. All the other armor pieces are built and just need to painted so stay tuned for the finished build!
