Jail Bird

The JAIL BIRD male chastity device is our most popular design. The stainless steel bars are very rigid. They will not bend or pinch. Combines comfort with security, and great looks. Has a very low profile that is easy to hide under clothing and is perfect for 24/7/365 wear.

The open design makes it easy to clean without removing the cage. This makes it possible to wear the device indefinitely. Great for Internet or long-distance relationships.

Very Happy

I have purchased and used various "plastic" devices over nearly 18 years with varied success. I had heard for awhile that getting a metal CB was better so I researched and choose MM. I got my JailBird a couple months ago and immedialty I discovered the advantages and will never go back to a plastic style. First and foremost - I knew the size I needed and MM was able to make it to fit like a glove. I have never gotten a fit this good EVER. The quality is amazing. This is the REAL DEAL!!! The steel is heavy duty, polished smooth and perfectly crafted. I personally got the security screw which eliminates all these different style locking mechanisms into something small and relatively easy to use. I even had them add an extra hole for a separate lock if my key holder desires. With this fit I can easily wear 24/7 and I can do all my normal activities. This Jailbird has a very high level of security so that there is no chance of getting out for me ( there is no other screw driver that will fit this without harming the screw) I also love the feel of the solid steel weight of the jailbird, enough to know it's there but never an issue or hurtful. Plasics are lighter but bulkier - this one is far less bulky and easier to wear. I am extremely happy and recommend to anyone. I wouldn't use any other company, MM service has been fantastic and wouldn't look elsewhere. The money is WORTH IT!!!

Followup review

I thought I would come back and do a followup review and found my original review from back in March 2014! Hard to believe I've been locked in my Jail Bird for over 4 years now! My wife only unlocks me when she wants to play with my penis and once a week to shave. Otherwise it has only come off for doctor visits and for flying. I am still just as happy with my Jail Bird as I was when we first got it and still believe it is the best chastity cage out there.

What cage, am i wearing something?

Am i wearing a chastity device, not really sure! That's how comfortable the MM Jailbird is. Order the sizing rings and let Mistress MM fit you for the cage you will finally be happy to wear.

Secure, lightweight, comfortable

I have been wearing the Jailbird for four days so far and it feels great and is very secure. I honestly think I can wear it nonstop for months. I have tried many different over the counter chastity devices and none fit as well for long-term use as this one. Incidentally, I've found that the Omtex Neo Athletic Cotton Gym Supporter available on Amazon provides perfect support for this device and others. I'm fairly active and walk to work 3 miles roundtrip every day. The device causes no problems in my daily walk or trips to the gym. I'm especially happy it is so concealable. I've worn it with jeans, business slacks and my gym sweatpants and it does not show at all. Since I'm in a long distance relationship, my girlfriend uses the Igloohome Smart Key Storage Lockbox to keep the key under her control, but yet available to me in case of an emergency or in the rare event she decides to let me out. When I first got the device my measurements were off, so I returned it for adjustment for the cage length and ring diameter. They made the adjustments and returned it to me in about a week. Thanks for the quick turn around. If you are looking for a comfortable chastity device that is 100% secure, comfortable for long-term wear and concealable, I highly recommend the Jailbird.

Best of my all chastity cages

I have tested over 40 different chastity cages. The Mature Metal Jailbird chastity cage is the best of them all. It looks like a juvel and it fits like a glove.

I did the measurements many times and I also checked the measurements for the holytrainer chastity cage I remember was longer than I was need but it was to small. So when I set up this order I was sure to go down in the length and increase the width.

Now I have one perfect chastity cage for permanent usage. My Master have control over the keys 🙂

It's easy to keep it clean and shape.

It's perfect for long distance locking.

I have chosen padlock 🔒 as locking options. I thought that was the best because you do not need to destroy the chastity cage if you need to emergence from it but don't have the keys.

Long fitting a big one

It's been many years now since I first put on my 2 1/8 X 1 7/8 X 3 3/4 Jail Bird. The only problem I've had is winter shrinkage. I'll soon be ordering a 2 X 1 5/8 X 3 for those cold winter months when my first one is just a bit too loose.

Other than My shrinkage, the Jail Bird has fit perfectly and comfortably for longer than I can remember. I'm not kidding. At my age anything past 4 or 5 years ago is the distant past.

The only reason that I have hesitated to order the "winter size" cage is that I want the base rings to interchange and that necessitates sending back the first one and it's uncomfortable to go without.

Most Comfortable Yet

After a year of toying with various metal knockoffs and a few plastic options I finally took the plunge and ordered a custom Jail Bird. Now I'm kicking myself for waiting so long. Plastic cages, although comfortable, present hygiene challenges. Metal cages didn't seem to fit right out of the box, and allow pinch points (especially where the pins enter the base ring). The Holy Trainer was/is great for short term wear or when needed for travel purposes, but nothing comes close to the Jail Bird. The measurements were exact and after a few hours I didn't even notice the cage during normal daily wear. It arrived two weeks ago with the security screw option. I haven't seen either key in that time and my wife seems happy to keep going...longer than any other cage so far, and easy to keep clean. MM rocks.

Comfort and fit far surpasses anything out there

I have enjoyed chastity cages for years. The Jail Bird by MM is simply amazing. The weight and feel of the metal is exactly what I've been looking for. The things I enjoy most. As a note, I enjoy self-deprivation or allowing another to hold the key. Longest I've been in chastity is 60 days with the CB6000 unit.

1. No pinch points (OMG this is worth it just for that fact-I've tried about 4 different models-all cheap)
2. Smooth "edges" as there are on sharp edges on the jailbird there are no chafing areas.
3. Easy maintenance to keep clean, unlike plastic shaft cages that can keep water/sweat in the metal cage allows for better air flow.
4. I have a 2 gage PA that is a continuous circle (screw type) I can wear it inside the cage, or actually hook the PA through one of the bars of the cage. I like it in that it keeps a flaccid penis elongated to the length of the cage. (also it tends to rattle which I find erotic when out in public)
5. For exhibitionist types, the ribbed cage looks amazing in jeans, for the shy, wear loose jeans (or whatever your Sir or Mistress tells you to wear)

Overall advice: Don't be cheap with this. Measure yourself multiple times over a week (I found my flaccid was bigger than my estimate) If you're in the rage to add the second or third circumference ring, do so, it looks better (IMO) and also keep the amount of access to the penis reduced, because trust me, a guy in chastity will find a way to nut, just saying, it can happen. LOL I added the security pin on mine, glad I did, a lock is nice, but the security pin is great.

This is an investment once you know you like chastity or the person you're putting in is ready. It is an investment worthwhile.

In love

To start this off, I've had my Jailbird for years now, and I've been in love with it ever since it first came in the mail! I've been an avid and serious chastity slave for a long time, and like most, I started out with those terrible plastic designs, the ones that are meant to fit all. Well, if you're reading this, you, too, have discovered that they might "fit", but they are far from ideal for anything longer than a 24 hour period. Nothing fits like a custom made device, and, in my opinion, nothing looks sexier than steel. Yes, sex appeal is a factor in how I choose my devices. There is just so much positive to say about this product and the experience behind making it, but I'll try to stick to the basics.
Customer service: Outstanding!! Seriously, they're very quick to reply and extremely helpful with any questions you might have.
Quality: It's just amazing, I really have no complaints here, as well. The craftsmanship is superb and the attention to detail is great.
Comfort: Even before I had the sizing of the ring fine tuned and the padlock replaced with a security screw (which I HIGHLY recommend), I was able to wear it for more than a year with little issue.

So, again, if you take chastity seriously and want the comfort to boot, this is probably one of your best options! I say this has been one of the best purchases I've ever made in life.
