sleep in zentai, is it ok?

a lot of people love to wear zentai for doing a lot of things. maybe some people are not familar with zentai, it is a tight full body suit that covers you fully, from the head to toe. and zentai is made from different materials, the lycra and spandex zentai suits are the most flexible, breathable and comfortable to wear, so most of people would like to choose lycra spandex ones, it is the most safe zentai suit to wear.
however, some people more like to wear the shiny metallic zentai suit that is less breathable and flexible, they do a lot of things in it, take this silver man as an example, he just likes to sleep in his shiny metallic zentai suit. of course, you can sleep in the zentai suit, but it's better for you to be careful and choose the most breathable lycra ones. anyway, the safty is the first place.
