The Top 11 Best Hollow Strap On Dildos For Men! (2024)

The best hollow strap-on dildos should be able to maintain their shape properly. If they’re too flimsy, they will be uncomfortable to use.

Stability, control during use, and comfort are crucial to avoid having the hollow strap-on dildo collapse or bend unexpectedly. Not only does this disrupt your experience, but—at worst—it runs the risk of causing injury to the wearer.

With so many options available, finding the right hollow strap-on dildo can be challenging. After testing numerous hollow strap-on dildos, I’ve compiled a list of some of the best ones that offer both quality and intense pleasure.

Key Considerations To Look For In A Hollow Strap-On Dildo

• Material and quality: When selecting a hollow strap-on dildo, get those made from body-safe materials like silicone, body-safe polymer, or plastic, as the choice of material directly impacts durability and safety. It’s also important to note that while plastic hollow body straps are body-safe, several counterfeit plastics are in circulation. Therefore, buy from a reputable manufacturer to ensure safety.
• Size and fit: Hollow strap-on dildos come in various sizes, offering an insertable length ranging from 6″ to 8″. Other models are customizable, allowing you to select your preferred length. The right fit should hold the penis firmly without compromising comfort. 
• Price: Prices can range from as low as $20 to as high as $500+. The difference is often due to material and sometimes length and girth. Generally, the higher the quality of the material, the more expensive the hollow strap-on dildo will be.
• Versatility: Versatility is essential in ensuring compatibility with other dildos and accessories. This enhances its usability. For instance, if the hollow dildo comes with a harness, check if the harness can accommodate dildos of various sizes, which maximizes options for experimentation and pleasure.
• Ease of use: Assessing how easy it is to put on, adjust, and clean the hollow strap-on enhances the overall user experience. Opting for a design that simplifies operation and maintenance provides a seamless and enjoyable sexual experience.

There’s so much to love about this strap-on set.

Secondly, the three interchangeable dildos give you an array of choices. 

This is great if the receiver is size training, if you have multiple partners with different preferences, or if you want the smaller options for pegging or anal sex. 

The harness is very well made and super sturdy. It’s comfortable and requires no adjustments during sex, so you can concentrate on enjoying yourself.

If you have the cash to splash and want the deluxe kit, you can’t look past this option.

Circumference:

Color:

Vanilla, Chocolate

Waist Size:

Stretchy

• Great value for money
• Wide base for a secure hold
• Quality hollow silicone dildo

• Only one size O-ring, so the harness won’t fit every dildo
• Harness feels cheap

If you had told me it was possible to find a decent-quality hollow strap for $39, I would have laughed.

Until I discovered this beauty of a hollow strap from CalExotics. It’s 7 inches of non-porous silicone with a stretchy harness that should fit almost anyone. 

This hollow strap really adds some length and girth with a 3-inch solid head leaving about 3.5 inches of internal length for you to fill. 

This 7 inch strap is comfortable and secure – no matter how hard you pound it shouldn’t slip out or move around awkwardly, which for a cheap extender is awesome. 

Honestly, at this price, it’s hard to come up with many drawbacks to this extender. The harness isn’t the best build quality and there’s only one O-ring. 

But then again, it’s still better than I would have expected. It really is the perfect extender for beginners for those who are looking into hollow strap.

Waist Size:

• Different sizes aren’t that different

The Doc Johnson Silicone Hollow Strap-On is the perfect upgrade for couples who know they like penis extenders and want the best. 

There are three different sizes to try out which I think of as Pretty Big, Big, and Very Big. 

All of the dildos are made of premium quality silicone so they’re non-porous, totally body safe and easy to clean. All you have to do is wash them in soapy water.

It’s even good for double penetration as there is a sizeable hole underneath the sex toy. Not to mention the dildos are stiff enough to use on their own. 

There’s also a rechargeable bullet vibrator built into the harness, which feels great for your partner during use. It’s strong enough that you can both feel it, but not so strong that it distracts from sex or makes you cum too fast. 

A great choice among hollow strap ons all around.

MATERIAL:

PVC, body-safe polymer

LENGTH:

10”, 11”

OUTER DIAMETER:

2.2”

INNER DIAMETER:

1.5”

COLOR:

Black

• Incredibly filling
• Four-way adjustable straps
• Comes in two different sizes
• Dual-density materials

• Only comes in one color
• PVC is porous
• Straps can be uncomfortable

If it’s the length you’re after, this is one of the biggest hollow sex toys on this list. 

It’s so big, in fact, that the harness comes with a shoulder strap to handle all that weight!

If you’re into bondage, this can be a huge turn-on. But depending on the position you’re in, they can also be uncomfortable and get in the way.

The dual density of the realistic hollow dildo means it feels like a realistic penis with a soft outer layer covering a rigid inner body. 

The internal canal features a removable tube, making it length-adjustable for those with larger penises.

Circumference:

Color:

Vanilla, Cashew, Caramel, Chocolate

Waist Size:

• Works well for STP
• Comfortable enough to use all-day

• Harness not included

This hollow sex toy is nice and soft, realistic looking, and functions very well as a stand-to-pee device (I’m told).

Those veins are nice and convincing to hold, too. Actually the attention to detail all over is great. 

The silicone material warms quickly to body temperature, making it feel much more real than something made of plastic. 

It’s light, comfortable, hygienic and cheap. As far as packers go, you could do a lot worse. 

This packer doesn’t come with a harness, so you’ll have to get a boxer harness to use it if you don’t have one already.

7. Fetish Fantasy Unisex Extreme Vibrating Hollow Strap-On 

Price:

$$

Material:

Plastic

Insertable Length:

8”

Circumference:

7”

Color:

Black, Flesh Pink

Waist Size:

16″ to 56”

• Easy to put on and secure fit
• Well-made harness
• Great for size lovers

• Needs a lot of lube
• Contains latex

Hope you like ‘em big… Because this thing will fill your partner up and stretch them out!

The faux leather harness of the Fetish Fantasy Unisex Extreme is a good one: It’s very easy to get on and off quickly, holds in place and looks good while you’re wearing it.

The Fetish Fantasy Extreme is hard enough to be used as a penis extender or as a strap-on for pegging, which is a nice touch of versatility. 

The plastic is harder than some of the softer silicone dildos, which might not be to everyone’s taste. With the hard plastic hollow core, it’s definitely firmer than a real erect penis. 

If you don’t like the hard plastic core of the realistic hollow dildo you can always remove it and just use the softer outer layer, which feels really nice. 

One thing to remember before you buy: this thing is BIG. Like, really big. 8 inches long is one thing, but 7 inches in circumference?

Don’t let your eyes get bigger than your stomach. Or holes.

Oh yeah, and the plastic contains latex. So make sure no one is allergic!

Length:

Internal Length:

Circumference:

6.25”

Color:

Purple, Black, Flesh Pink

Waist Size:

38”

• Sturdy but not too hard
• Doubles as a pegging toy (if you can take the size!)
• Affordable

• Big and no choice of size
• Smallish waist size limit

If you want a penis extender, you want your enhanced to look good, right? 

This is the toy for you. This Perfect Partner Unisex Hollow Strap-On by Lovehoney is a pretty strap-on. It’s long, thick, has nice rippling and the purple color especially is gorgeous!

It has a powerful vibrator in the tip which mainly stimulates the receiver. That said, it’s strong enough to vibrate down the shaft and tingle the penis very nicely. 

Shame that it’s battery operated and not rechargeable, but at this price that’s hardly a complaint. 

It’s thick so any penis around average length should fit inside easily.

Plus, it’s rigid enough to use as a pegging toy — although it’s so thick that you might struggle unless you’re already a veteran of butt stuff. 

9. Blush Dr. Skin Hollow Strap-On

PRICE:

$

MATERIAL:

PVC

LENGTH:

7”

CIRCUMFERENCE:

5.49”

COLOR:

Black, Flesh Pink

WAIST SIZE:

40”

• Super comfortable wide-strap harness
• Nice textured shaft
• Very firm, but with some flexibility

• Might be too rigid for some people
• PVC is porous

If you’re into SIZE but don’t want to go overboard, this hollow strap is generous without being overwhelming.

It’s made from phthalate-free PVC, which makes for a very rigid dildo. 

However, some people do find it to be too hard. 

If you suffer from any mobility issues, the firmness of this hollow dildo can help keep it in place without much need for thrusting.

For the wearer, the harness is a dream. 

The wide hip strap is incredibly comfortable and secure. And even for average-sized penises, the internal canal doesn’t feel restrictive.

The biggest downside is that PVC is a porous material. 

If it’s not cleaned properly, it can harbor bacteria. 

Use a condom if you plan on switching between anal and vaginal penetration.

10. Fetish Fantasy Ejaculating 7.5 Inch Hollow Strap-On

PRICE:

$$

MATERIAL:

PVC

LENGTH:

7.5”

CIRCUMFERENCE:

6.25”

COLOR:

Flesh Pink

WAIST SIZE:

Up to 52”

• Highly adjustable harness
• Comfortable wide straps
• Can be used with any body-safe ‘ejaculate’
• Very realistic
• Fits smaller penis sizes

• Only comes in one color
• PVC is porous
• Can collapse slightly on wearers who don’t have a penis

If you’re going for a super-realistic experience, this 7.5 inch hollow strap-on toy is the whole package (pun intended). 

The realistic hollow design of a dildo sells the idea that this is your own penis (as long as you have pale skin), and the ejaculating feature means you and your partner will get the full experience. 

You simply squeeze the end of the penis to shoot your load wherever you want.

This is specifically designed for people with penises below the average. 

It will be most comfortable if your erect length is around the 4-inch mark. 

However, if you don’t have a penis, this might not work well for you. 

The hollow base means that, unless you have something filling the shaft, it tends to collapse in on itself with thrusting.

• Includes a mask

• Can be too rigid for some people
• PVC is porous

This hollow extender offers a little texture for the receiver, bringing more stimulation into the mix.

This Feitsh Fantasy Hollow Strap is an affordable choice, making it great for beginners. Plus, the glow-in-the-dark color option is a personal favorite. 

I didn’t know I needed a glowing cock until this moment.

The PVC hollow dildo of the Fetish Fantasy Unisex Extender is quite rigid, though, so make sure your partner is into that before getting this bad boy. (That goes for the glow-in-the-dark feature too…)

What Is A Hollow Strap-On?

Hollow strap-ons is a dildo with a hollowed-out center so it can be worn over a penis. 

Most models come with a harness, so you can strap it on securely.

The great thing about hollow strap-ons is that they can be worn by people of any gender – you don’t have to have a penis to wear one. 

However, hollow strap-ons most often used by people who want to add extra girth, length, rigidity, or stamina to their own penis.

Why Use a Hollow Strap-On?

If you experience erectile dysfunction (ED) or premature ejaculation, hollow strap-on dildos could be a game-changer. 

Hollow strap-on dildos can be worn over either an erect or flaccid penis, so if you have ED, they’re great for taking the pressure off. 

Hollow strap-on dildos can help you relax as well as reduce performance anxiety.

If you experience premature ejaculation because of over-sensitivity, these hollow sex toys can reduce stimulation to your penis. If you’d like to last longer or stay hard even after you cum, a hollow strap-on can help with just that.

To extend the length or girth of your penis, this is just the hollow sex toy for the job. You can choose how much you’d like to add to your penis length and find the best hollow dildos to match.

Because hollow strap-ons can be worn by anyone, they’re incredibly versatile. Hollow strap-ons are great for pegging, trans folks, and WLW couples.

Types of Hollow Strap-ons

There are three kinds of hollow strap-ons, each with its own advantages and disadvantages. Let’s see which one might be best for you:

How To Use a Hollow Strap-on

Those who haven’t used a penis sleeve before have this vague idea that your cock needs to be hard to put it on.

Well actually, most hollow strap-ons work best if you’re semi-hard.

And some hollow strap-ons are actually designed for men suffering from ED, so they work perfectly with no erection at all.

The most comfortable way to put a hollow dildo on is to apply the best sexual lubricant inside and then just slide it in.

Squeeze out the extra air, and you’re all set. 👌🏻

Harnesses add additional security when erection is an issue, as the straps help the dong stay in position while thrusting. 

A few extra tips on how to use a hollow dildo:

• Warm it up in warm water before as it’s not body temperature and will feel cold
• If the dildo is larger, missionary with your partner on top will be the best position (let her control the pace)
• Use high quality water-based lubes, because oil and silicone-based lube can damage plastics and silicone toys

How To Clean & Maintain A Hollow Strap-On

For most strap-ons, cleaning is as simple as using warm water and some mild soap or sex toy cleaner. 

You must clean the inside thoroughly. You can use your fingers to ensure you get into all the nooks and crannies.

Check the manufacturer’s instructions for cleaning, especially if your hollow strap-on has any electronic parts like a vibrating motor. 

After cleaning, let your toy dry thoroughly before storing it in a cool, dry place from direct sunlight.

Conclusion

A hollow dildo can add whole new dimensions to your sex life, but there’s a lot to consider before you just shove it in.

Do your research and don’t forget to have fun out there with your hollow straps!
