Let’s jump in:


Perfect Fit Zoro 6.5"

1. Perfect Fit Zoro 6.5″ 

The most comfortable & realistic feeling hollow dildo

Material: Silicone | Length: 6.5” (inches) | Insertable length: 6.5″ | Circumference: 5″ | Color: Black

  • Extremely comfortable, no messing with strap adjustment
  • Versatile – can use for DP, to help with Ed.
  • Simple, intuitive design
  • Cannot change to different size hollow dildo (one piece design)
  • Position of opening under hollow dildo might not work depending on your anatomy

Considered as the most comfortable and realistic strap-on dildo on the market, the Perfect Fit Zoro 6.5″ comfort can only be compared to that of a real extension of your body.

While comfort is attributed to its ability to accommodate almost any size, hollow dildo soft silicone material makes it feel like a real penis. 

The design itself is very simple and thought through:

Harness and hollow dildo is one piece, waistband is stretchy and will fit most people (I’m 34″ in waist and it stretched easily).

It really feels like it’s part of your body, you will forget it’s there. No sharp edges, it just ticks all the boxes.

Oh, and there is a space for a bullet vibrator in dildo’s shaft too (not included) if you want to upgrade later to vibrations.

There is a reason why this item is the #1 selection.

You can use it for double penetration, to help with ED. The only reason why this might not be a good choice is… if you care about huge size and girth increase.

For that take a look at #5th Fetish Fantasy hollow dildo.

Oh, Zoro is stretchy enough to be positioned even over chastity making it fun for denial stuff too.


Calexotics Silicone Hollow Strap-On Dildo

2. Calexotics Silicone Hollow Strap-On Dildo

The best budget pick

Material: Silicone | Length: 7” | Insertable Length: 6.5″ | Circumference: 3.5″ | Waist Size: Stretchy | Color: Vanilla, Chocolate

  • Great value for price
  • Dildo is made from quality material
  • 90-Day warranty
  • Harness is cheaply made
  • Only one O-ring, which means it won’t fit all the size dildos.

Sometimes you may not be sure if hollow dildo strap on will work for you.

Which is why this Calexotics hollow dildo with jock strap harness is a steal.

For $33 you get a stretchy harness that you can use with other flat base dildos and silicone hollow dildo.

It’s good to use even while you’re not flaccid as it has 3″ long solid head at the tip of the shaft.

It really adds the length and a little bit of girth, which you might appreciate it you’re on the shorter side.

Another handy feature is it’s wide base that really ensure that the hollow dildo holds securely and feels comfortable.

My only comment is that harness could be more solid, but for the price I do think it’s a great deal.

Keep in mind this is a 7″ dildo (when average penis size is 5.16″). If you’re not a size queen it might be too big.

On the flipside, if you’re average sized yourself, you’ll need a bigger hollow dildo anyway.

Make sure you measure yourself (girth and length), compare with the hollow dildo and make a call if it will be a good fit for you.


Doc Johnson Be Naughty (4 Piece Kit)

3. Doc Johnson Be Naughty (4 piece Kit)

The most versatile

Material: Silicone | Length: 7” | Insertable Length: 7″, 7.5″ and 8″ | Girth (widest point): 6″ and 7″ | Waist Size: 28-48″ | Color: Black

  • 3 different size interchangeable silicone hollow dildos and 1 harness
  • Well made product
  • Great for DP because of opening under hollow dildo
  • Pricey, but good value for price
  • Quite big hollow dildos (unless you like it)

You can upgrade to this Doc Johnson harness if the Calexotics Silicone Hollow Strap-On Dildo is below your standards.

It’s tricky to measure for the right size for hollow dildo as there are many factors in play – stretchiness of dildo, your penis size, girth…not even talking about what size your partner would prefer.

Which is why it’s nice to have several size options available from the start. There is simply so much less room for error.

3 size options will open the room for play with size increase, and also for times when you’re tired and flaccid.

This is a quality product, easy to use, even though some people complain about the internal circumference of the two smaller size dildos.

They might be too small for you if you’re up to 5″ circumference when erect.


RX Sleeve

4. RX Sleeve

The best strap on penis for ED in market

Material: Silicone | Length: 5.5″ – 9.5″ size options | Insertable Length: 1″ less than overall length | Circumference: Customisable | Firmness: Soft & Firm | Color: Vanilla, Caramel and Coco | Waist size: adjustable up to 60″

  • Many size options, only company that make custom fit internal dimension sleeves.
  • Highest quality, realistic feeling, works great
  • Pricey, expect to say goodbye to aprox $400

When you cannot get and stay hard to satisfy your partner it really hurts your sexual self-confidence, even studies have proven that.

But what are your treatment options? Choices for fixing ED for a long-term are poor.

Yes, there are pills, but the side-effects are questionable.

Which is why a hollow strap-on dildo might be a good solution. It doesn’t fix the ED, but you’re still the one driving the thing.

And it feels pretty powerful. I don’t have ED problems, but there are times when she wants me to keep going… I want too, but penis refuses.

This is when item like RX Sleeve comes handy.

Marketed as the only FDA approved penis extender company, it’s undeniably a quality ED solution.

But it’s really pricey. For example, Zoro still does pretty much the same thing, but for a lot better price.

If money is not an issue and you want the best there is, only then I would consider RX sleeve.

It does feel great, looks realistic and will last you a lifetime.


Fetish Fantasy Extreme Hollow Strap-On Dildo 8"

5. Fetish Fantasy Extreme Hollow Strap-On Dildo 8″ 

The biggest size and girth hollow sleeve

Material: Soft plastic | Length: 10.5” | Insertable Length: 8″ | Circumference: 7″ | Waist Size: 16-56″ | Color: Black, Flesh Pink

  • Strong harness for bigger toys, can use with other toys
  • Great to use on size queens while staying on budget
  • Soft Plastic material, not the best quality material
  • Crotch strap could be bigger for more comfort
  • Contains latex

If you’re attracted to big size and girth, it doesnt get much better than this. Both harness and dildo look like it’s made for heavy-duty action… and it is.

While I don’t like it’s made from plastic, and not silicone, know that for big size silicone dildos also get pricey. But here you get harness and hollow dildo for $80+.

Let’s start with harness. It’s comfortable, says in place well and is very adjustable for perfect fit.

The only flaw in design is the narrow crotch strap. You might want to pad it a bit more.

Now about the dildo. If you’re average sized, you’ll want to remove the hard inner tube.

But remember that tube when you want to play while flaccid ;).

Due to it’s large size the best position will be basic missionary with woman on top.

And be careful, use lube both on the inside and outside to prevent any friction.

Oh, and while we’re at it, make sure you push out any air from shaft when inserting it.

Material feels surprisingly well and if it’s your first hollow dildo venture in size play, this might be a good option.


Fetish Fantasy Elite 6"

6. Fetish Fantasy Elite 6″

Best vibrating hollow strap on dildo

Material: Silicone | Length: 6” | Insertable Length: 4.5″ | Circumference: 1.75″ | Waist Size: fits up to 56″ | Color: Purple | Power Source: AAA batteries (not included)

  • Good quality vibrating hollow dildo
  • Fairly priced
  • Small plastic straps, cannot use harness with other hollow dildos.
  • Not rechargeable (unless you have rechargeable batteries)

This set packs a lot of good things for a reasonable $60+ price.

You’ll get adjustable harness (made from plastic), a high quality silicone hollow dildo and a remote for vibrations.

You can easily attach the remote to the harness, and while it’s not the comfiest option (because of wires) it does work good enough.

This is not a great, nor it’s a bad kit, but it ticks many boxes for experimentation (at a fair price).

If you have a better bullet vibe, I would look at Zoro (our #1 selection) though, as the intensity and vibration quality is ok, not great.

But this is a bundle – you get all in one package.

Dildo is rigid enough to support flaccid penis, but I would warn you to measure carefully to get the size close to yours so the wearing would be comfortable.


Calexoticts Soft Hollow STP Packer

7. Calexotics Soft Hollow STP Packer

Best packer for trans people

Material: Silicone | Length: 4″ | Insertable Length: 3.5″ | Circumference: 4.5″ | Waist Size: no harness | Color: Skin-tone, black, dark brown

  • Looks and feels super realistic
  • High quality item for a good price
  • Takes a bit of practice to use as “stand to pee”
  • No good instructions on how to use
  • Too soft for some who are looking a big bulge

Keep in mind, this is just a packer dildo, you’ll need a boxer style harness with this.

If bending or squatting to pee is not your thing, consider getting the Calexotics Soft Hollow STP (stand-to-pee) Packer dildo.

See…

Because of the silicone material, this STP warms up quickly to the body temperature, making the experience of standing up to pee very natural and thrilling.

Besides the squishable silicone material, the STP’s head and balls are realistic and feel authentic and just like the real skin, increasing your confidence in peeing naturally. 

Don’t be afraid of the size because the bowl is large enough to hold urine while snugging perfectly around your balls to avoid any leakages or overflows.

It comes with a detailed shaft to direct the flow of urine from the bowl, just like the real dick would do.   

While this STP is good at addressing anatomy issues, you need to do some practice before you can get used to using it effectively.

In addition to this downside, the toy cracks easily due to storage or boxer issues. 


Finally, after finding a good hollow dildo you might want to upgrade to better harness ( if hollow dildo is detachable).

You should consider the Spareparts Deuce Male Harness which is compatible with any hollow or strap-on dildo of your choice.

This is the most comfortable and adjustable harness for men that is available on the market.

Also, consider trying out the Strap-On Me Squirting Dildo that can be paired with the Spareparts Deuce Male Harness to create a perfect combo for you (for DP or squirting play).

And now…

Let’s move to additional tips on how to choose and wear the hollow dildos:


How To Choose The Best Hollow Strap-On Dildo For You?

Now that you know the best hollow strap-on dildos, it is time to figure out how to select one that will work the best for you and fulfil your specific desires.

What Types Of Hollow Strap-ons Are There?

  • one piece harness + hollow dildo design – this is the most common design if you’re looking for a budget option. The upside is the price, the downside is that you cannot mix and match other dildos.
  • interchangeable dildos and/or standalone harness – this is the best long-term option. Some harnesses work only with their brand-specific hollow dildos, but the best ones have an O-ring harness that you can use with other hollow or flat base dildos.
  • hollow vibrating strap on – it is as it sounds, an added vibrator to action. But added vibrators usually are low quality, a lot better option is to either look for hollow strapon with a space for bullet or simply add a vibrating cock ring with it.
things to consider when buying a hollow strap on

Few Tips On Choosing The Right Size (length and girth)

This is the most important precaution that you must make, as the wrong size or girth will make the sex toy useless.

  • consider your size vs hollow dildo size/stretchability so it fits – Measure carefully you size and then compare with your desired hollow dildo. Most dildos are made with average penis size in mind, but on top of that you need to check how rigid or stretchy dildo is. It also matters if you’re planning to use dildo with flaccid or erect penis.
  • talk to your partner before – you might think it’s a nice surprise, but she might be tight and too big dildo might not be desired. Communication is crucial to avoid disappointments and wasted money.
  • careful: many hollow strapons can be too big added size, which is usually bad unless she’s a size queen – if you’re planning to use a hollow dildo when erect, be careful and avoid “size bigger than eyes” dilemma. Err more to the side of conservative than too big.

Consider Your Preferred Dildo Material, Shape, & Feel

Hollow dildos come in different angles, with defined head, without, with ridges, veins etc.

Think back of what you liked in past (or your partner), and if unsure go for simpler dildo design.

But, for example, if she loves G-spot stimulation, a curved dildo might be a must.

Material Consideration

You can never go wrong with silicone as it’s non-porous, body-safe, and overall is the best option.

if you like bigger sizes however silicone gets pricey which is why many people opt out for a lot worse PVC, TPR material, that may cause bad reactions in body. Not recommended.

Plastic material technically is body-safe, but it’s tricky. You don’t know what material concoctions hide behind that name “plastic”.

How To Get The Right “Feel”

it’s very tricky. For different people, different firmnesses feel different. My best advice is to find a product video (Lovehoney usually has one) and look how soft, jellyish, rigid dildo feels.

Keep in mind if you want to use it while flaccid, you’ll need more rigid material and you might need to compromise a bit on realistic softness feel.

Zoro (#1) item in list has been striking the best balance of rigidness and realism, in our opinion.


steps to take before putting on a hollow strap-on

How to Use a Hollow Strap On Dildo (Step-by-Step Guide)

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

That’s so far from the truth, as actually you need to be ideally semi-hard or even flaccid to have the best result. 

As you could see, some are actually designed for those men suffering from ED which assumes that there’s no erection whatsoever. 

The most comfortable way to put it on is to apply sizeable amount of lubricant inside (but not too much or it will not stay in place) and then just slide it in.

The extra amount of air should be squeezed out, and you’re all set.

Harnesses add additional security when erection is an issue, as the straps help the dong stay in position so that it doesn’t get loose.

A fun thing you can do with these hollow strapons is to use them while being in chastity.

You won’t feel much when wearing the sleeve so why not have more fun with it?

A few extra tips on how to use hollow dildo:

  • warm it up in warm water before as it’s not body temperature and will feel cold.
  • if dildo is on bigger size, missionary with your partner on top will be the best position (let her control the pace)
  • avoid using silicone-based lubes with silicone toys, most don’t play well together.
