This product has been discontinued and replaced with our improved Clear House Trainer V4 chastity device.

We’re very happy to welcome the latest version of our best selling chastity cage; the clear Holy Trainer V4. It’s the most discreet and secure device in the range and is available right now in 5 sizes; maxi (the largest), standard, small, nano and the tiny nub cage for the pin dick losers amongst you. All of our kits come in a smart zippered storage bag and four back rings with internal measurements of 36mm, 40mm, 45mm and 50mm.

The soft and smooth material is comfortable against your skin, which will allow you to remain securely locked for days, weeks or even months at a time. Don’t worry though, every time you try to get an erection the clear Holy Trainer V4 will quickly stop it and prevent you from getting any sexual pleasure until either you or your keyholder unlock the cage.

Speaking of the lock, the hidden locking system is back. Our Holy Trainer V4 kits come with a sliding lock and 2 keys, so you can keep one for yourself while your keyholder proudly wears the other one around their neck to tease you.

The new thicker back rings are designed specifically with comfort in mind, specifically when it comes to night time erections. The ergonomic design will make it easier to get through the night without waking up from the pain some rings cause when they pull forward as you try to get erect. So if you want a chastity cage to wear for long periods of time this is a fantastic option.

Keeping your cock clean while you’re caged is of paramount importance and with this device you can wear it in the shower and wash yourself thoroughly.

The Holy Trainer v4 is also available in black and pink, so if you want to hide your cock away or present it to your Master or Mistress in a cute sissy pink cage we also have these options.


Cage Length - 65mm (maxi), 55mm (standard), 45mm (small), 35mm (nano) or 25mm (nub).

Brilliant deice great value for money

This is night and day better than my last cage which was metal with a physical padlock. By comparison that felt like a torture device compared to this.

the Holy Trainer V4 is VERY comfortable, doesn't pinch or hurt at all. even when you try to get erect, it causes very little discomfort. I wore this over night last night for the first time with no underwear to support it and slept fine only waking up once with my pecker realising it needed to calm down.

Very comfy
Very discreet
and no noisy padlock clicking around.

Perfect design would definitely recommend and buy again


I can echo what some previous reviewers have stated as far as quality over the alternatives. The design is far more comfortable than any chastity device I’ve previously owned. It gets high marks in ergonomic design as well as concealment. I have both the short version and the standard. The short conceals better, the standard fits better. Both are excellent at preventing stimulation. The only thing I knock it on is poor ventilation. Moisture tends to be an issue. It’s the only thing preventing true long term for me. I also want to say that this site is stellar and I am highly pleased with my purchases thus far. They’re very helpful and I have no qualms recommending them to anyone interested. I’m looking forward to future purchases!

Perfect chastity device

I have previously worn and really enjoyed my CB6000S but it was a bit obvious under clothing as I have a stocky build so it bulged out. After a few years the flimsy design finally gave way so I found the Holy Trainer V4. It arrived today and it is fantastic. Very simple design and the whole thing is incredibly comfortable. It keeps me all squashed together and is invisible under clothing as well as being silent without the rattly padlocks (although I did enjoy that). Everything is top quality but it’s worth mentioning that the clear version does have quite a distinct blue tint to it. You can see it in the photos but it isn’t just an optical illusion it is quite blue. If that isn’t for you then you might prefer to go for the deliberately coloured versions. Top service from HoD with perfect next day delivery and discreet packaging. I’m a first time customer but it won’t be my last!

What a great product!

I bought this in January this year and have worn it full time almost the entire time since it arrived. It is, by far, the most comfortable of cages I have ever worn since 2005. It makes me feel even more restrained and secure, better than even the V3. Thanks a lot for that!!!


I bought standard for myself. I wear it all of the time between meets with my partner, as we don't live together. My erections are harder and orgasms intense. I could unlock anytime but don't as the sensation of denial is so horny.
