An efficient and discreet male chastity device

HolyTrainer will provide you with incredible ease of use and total security over a long period of time. Discover, through our website and our videos, the multiple innovations that have been made to chastity cages for men.


An innovative design

As for ergonomics, you just need to look at the ring to understand that its shape is perfectly suited to the male anatomy. Look closely at the device and its system of closure. The device for men is attached very easily and once the system has been closed, the tube is firmly attached to the ring.


A safety device

Its locking system and its materials makes it a product that is nearly indestructible. You can use the device during sports, sleep on your stomach or be attached to something. It will withstand all your desires while remaining firmly in place. Our Bio-resin will absorb any impacts without breaking and won't cause injuries to the skin.


Nighttime erections

You know what happens with most male chastity models. A nighttime erection pulls on the scrotum and causes pain on its base. With HolyTrainer and the ergonomic design of its ring, we guarantee you an excellent comfort without pain. In general, after 24 hours of use, you will have forgotten that you're wearing a male chastity device. The shape of the tube is also designed to discourage erections. Aimed downward, the orientation of the device does not favor stimulation. The chastity device remains very discrete beneath your underwears, even under close-fitting pants.


Hygiene & cleaning

The design and materials used makes it easy to clean. To wash it, you may simply use soap under the shower or put the male chastity device in the dish washer. It is very strong and will withstand exposure to alcohol or any other solvent. The air holes allow a very good venting. The skin breathes well and the opening located at the end of the urethra makes it possible to urinate comfortably.


Use over a long period

Our device may be used by beginners or experienced users. Since the tube allows the skin to breath, it can be worn over a long period of time. The materials used are 100 % hypoallergenic and will be completely tolerated by the skin, even during a long period of use.



HolyTrainer comes with a small bag. You can place the HolyTrainer on the nightstand in complete discretion. But don't be mistaken, even if the packaging is discreet and devout, its content will make you give up your sexual freedom with an iron fist. The device is provided with two keys and a "MagicLocker" made of brass that is resistant to water.


HolyTrainer, the new CB Killer

HolyTrainer, the new CB Killer?

Yes, I think that the HolyTrainer is the new CB Killer!
Sold at the same price as the competitors, it offers strength that passes the test, which is not really the case with devices made of polycarbonate. Imagine what would happen if a plastic device broke with your penis inside! Light and very discrete in comparison to metal devices, it proves superior comfort while offering the same security and impossibility of stimulating the penis. Lastly, it's the only device that guarantees that the materials used are 100 % natural and totally safe to expose to your skin.
