The Warmth Preserver is a community-created cosmetic item for the Heavy. It turns the Heavy's default vest into a padded vest with a collar and a zipper. The vest's shoulder part and collar are team-colored while the lower portions are dark and the zipper is white. The vest's back part is unchanged from Heavy's default vest.
