The Vice Plus male chastity cage is the most comfortable penis chastity device in The Vice Series. Men in chastity prefer The Vice Plus over the Holytrainer. With a larger diameter, and longer tube, this penis cage is more comfortable than The Vice Standard (for most)!One of the biggest factors to consider when choosing a penis cage is comfort closely followed by security. Still providing the unmatched level of security one expects from The Vice, this male chastity cage gives men in chastity more room to grow during an erection - which can be equally pleasurable and frustrating! If you are looking for a male chastity cage which is more restricting, you may wish to look into The Vice Mini. Penis chastity has many dimensions of fun, and you can explore all of them with the different size cages and other sizing options available.

Not only do you receive multiple sizes with every device you order (see sizing below), but you also have the piece of mind of a truly secure device you will not get out of, backed by a 1 year manufacturer's warranty. The sizing allows you to customize your penis cage to your anatomy, giving you the maximum comfort and security. Also allowing you to have a sizing kit in one purchase, without having to pay for every trial and error discovering your size.
