Anyone can use a vac-u-lock, most harnesses that support the vac-u-lock system are made unisex. That means that it’s possible to wear it no matter what sex you are. Although some don’t have space beloved where the genitals are it means it won’t be comfortable for people with penises to wear them.

If you are looking for sensational penetration, this is your chance! It’s pretty much the only set you need, after all, it’s a 13-piece strap-on kit.
This is included with your vac u lock strap on: 1 x 8-inch dildo, 1 x 7-inch dildo, 1 x slimline dildo, 1 x 7 function vibrating plug with remote, 1 x water-based lubricant, 1 x toy cleaner, 1 x Doc Johnson Vac-U-Powder, 1 x ULTRASKYN Refresh Powder, 3 x O Rings, 1 x adjustable harness, 1 x swiveling hands-free base.
It’s a mix of life-like dildos and straight-shafted ones, possibilities to attach vibrations and a nice realistic skin feel.
The Doc Johnson Vac-U-Lock Vibrating Dual-Density Ultraskyn Harness Set was rated 50 out of 100 meaning that it is most suitable for someone with some experience
| Harness Size | Up to 69" inches |
| Vibration modes | 7 |
| Materials | Realistic, Thermoplastic Elastomer |
| Length | 8,7 & 7 inches |
| Diameter | 1,75, 1,75 & 1,75 inches |
If you buy this set you will literally be set for life, it’s great for the ones who are a bit more experienced due to the sizes of the dildos. Besides that this set is for everyone, no matter if you like realistic dildos, straight dildos, or vibration.
The only minus we have is the harness, it’s got a pretty boring and basic look. For a vac u lock strap on set this extra it’s a disappointment. But I guess, it is compensated by the feeling.
Vac-U-Lock Ultra Harness With Plug
This is one of the cheapest vac u lock strap ons you can find on the market, it has got a simple and discrete design. It doesn’t have a lot of straps and it’s got one adjustable buckle for the waist strap. Good to know is that there are not any dildos included, only a small adapter plug to attack a vac-lock dildo.
It is designed with an open crotch and it leaves enough space for people with penises to wear this vac u lock strap on.
The price has its reasons, it is a good vac-u-lock but not as good as the previous one. Here you don´t get any extra dildos, it’s just the harness. The quality isn´t as good, but still good enough for the one who wants to just try a vac u lock strap on before spending a lot of money.
It’s very easy to use and suits best with small dildos, it gets a bit unstable when using heavier dildos. Great for a newbie to explore pegging and other kinds of strap on play.

They are also all of different textures, one is smooth with a realistic phallic-looking design, the other two have ridged surfaces that will stimulate during thrust movements and one of them has a pair of testicles too.

| Length | 7,6 & 5,5 inches |
| Diameter | 2, 1,5 & 1,5 inches |

With ultraskyn material, a material that makes the dildo have a pliable exterior with a firm inner core these dildos feel very realistic. Thanks to how easy they are to handle it’s great for beginners, even though it is still good to find an even smaller dildo to use for warm-up.
It quickly warms up to body temperature and when it comes to being waterproof it’s submersible. It’s made out of TPE and therefore, compatible with a lot of different lubes and there is one lube included.

Looking for something big, girthy, and fleshy? Here we got a big vac u lock strap on for experienced users. It’s a kit where you get everything you need from dildos to toy cleaners. There are three different dildos, two with veiny shafts and all of them with pronounced heads.
The storage box the set comes in is great to keep for easy storage after use. When using big vac u lock strap-ons like these, lube is a must! Luckily there is lube included, but you will most probably need to buy some more.
The Doc Johnson Vac-U-Lock Realistic Feel Advanced Strap-On Dildo Set was rated 75 out of 100 meaning that it is most suitable for someone with some experience
| Harness Size | Up to 69 inches |
| Insertable length | 10, 8, 8 inches |
| Materials | Soft Plastic |
| Waterproof | Splashproof |
This is definitely not a vac u lock strap-on for the beginner. The three dildos are big and therefore it’s also not really naturally positioned, this means it might be a bit difficult to get the powerful thrust motions going.
The harness is comfortable and the back straps are wide for minimum chafing and maximum comfort. The straps are easy to adjust even when wearing the harness thanks to the wide back strap.
Black Double Penetrator Vac-U-Lock Attachment
This is for you who always want more and can’t get enough – the double penetration vac u lock strap on, it’s got two dildos for maximum intense pleasure. It’s created for people with a vulva to experience the ultimate fulfillment.
There is one bigger dildo, which we call the “main dildo” that goes into the vagina and one slimmer dildo meant to be used as an anal dildo. Both dildos have got raised veins on their shaft with clear heads, the anal dildo is a bit more flexible than the main dildo.
This double-penetration dildo can be used both for solo orgasms and partner play, be aware that it doesn’t include a harness, this is a reason why the price is so low compared to the other reviewed products.
It’s not for beginners, it’s good if you explored at least anal play before and maybe tried out double penetration once or twice. The anal dildo is very flexible which makes insertion easier for you.

| Materials | PVC Dildo, Vinyl Harness, ABS Plastic Plug |
| Length | 7 inches |
| Diameter | 1,7 inches |
| Insertable length | 6,3 inches |
This vac-u-lock-strap on does not have any straps for the butt checks which means it can be a bit difficult to get it to stay in place, it’s not as sturdy as some other strap-ons. Therefore, it can be a bit difficult to do powerful thrusts.
Remember that if you get tired of your realistic dildo you can always change to another vac-u-lock product and explore more.
