Skin tight suits that cover the entire boy are commonly called zentai (from the Japanese ゼンタイ). This is either a contraction of zenshin taitsu (全身タイツ) ("full-body tights") or a direct translation of "full body" (全体 zentai). Zentai is most commonly made using nylon/spandex blends, but other materials such as cotton and wool are used as well.
