For Jason's wardrobe, Mears was given a pair of combat boots and a "high-priced t-shirt" that allowed the special effects make-up to be seen through holes in the shirt. The jacket Jason wears in the film was created by combining a hunting jacket and a military jacket. Mears wanted to use the hunting jacket, but the creative team liked the way the military jacket billowed as he was making his "kill movements", so the top of the hunting jacket was removed and placed over the top of the military jacket to create what Mears called a "giant Frankenstein jacket." He describes Jason as leaner in this film because the character does not eat much. A leaner Jason was deemed more functional and allowed more emphasis to be placed on the hump on his back. Stoddard was inspired by the third and fourth films when designing Jason's hockey mask. Using an original mold, Stoddard made six new versions of the mask. He said, "Because I didn't want to take something that already existed. There were things I thought were great, but there were things I wanted to change a bit. Make it custom, but keep all the fundamental designs. Especially the markings on the forehead and cheeks. Age them down a bit. Break them up."
