What is Zentai?

Zentai is a term for skin-tight garments that cover the entire body. The word is a portmanteau of zenshin taitsu ("full-body tights"). Zentai is most commonly made using nylon/spandex blends, but other materials such as cotton and wool are used as well. And for zentai suits, the lycra spandex zentai suits are the most comfortable to wear, what is more, the lycra spandex zentai suits are elastic enough, and you can wash them with cold water. If you like sleeping in zentai suit, I think that lycra spandex zentai suits just can bring you a comfortable and casual feeling, when you are in zentai.
