SpareParts Hardwear Deuce Harness


SpareParts Hardwear Deuce Harness

The Deuce is the very first strap on harness from SpareParts HardWear that is especially designed for men! 


The stylish Deuce is a comfortable and durable dildo harness. Adjustable velcro straps fit securely and remains in place, providing complete control.  The leg straps cross at the perineum, therefore applying a light pressure to the prostate region allowing for additional stimulation. The pouch is designed so that it comfortably cups the testicles and penis if desired, without any chaffing or pinching. 


The Deuce has an elastic and stretchy O-ring which expands and contracts to hold a variety of dildos. A second hole just below the O-ring is lined with soft stretchable elastic, which accommodates the natural girth of the wearer. This subtle touch to this unique luxury harness, allows the second opening to act as a soft penis ring providing another pleasurable dimension when using the Deuce. 

Both openings have two small flaps on the inside of the harness so you have the choice of having the dildo base against your skin or you can have it covered for a more gentler, less abrasive sensation. With the flaps, you can also opt to have your penis inside or outside the pouch allowing you to enjoy the Deuce in many fun ways!

The simplicity of the Deuce means it makes it easy to use for a variety of ways. The wearer doesn’t have to remove the Deuce to insert their penis or the dildo through either one of the holes, while they are wearing it. They can simply release the belt strap and pull the pouch forward and insert or pull forward on either side of the pouch to insert. 


For an additional vibration, the flap for the top dildo can accommodate a wireless mini bullet vibrator. Vibrating penis rings can also be used with the Deuce for a further titillating sensation to the dildo and to the penis.


It’s also a fantastic choice of strap on for men who have erectile dysfunction. The versatility of the SpareParts HardWear Deuce Harness means it can be used with only a dildo or with penis and a toy simultaneously for dual penetration and double the fun.




You should be able to select a size that is reflective of your pant or belt size. So if you wear a size 34 in pants, and they fit you securely, you should select the Deuce that best fits 34 inches. You should add a few (3-4) inches to this measurement for size fluctuation and room for sizing adjustment.

Step 1
To measure which size is best, first figure out where you will be wearing it on your hips using a regular belt. 
Step 2
Take the tape measure and start by taking the end of it and holding it in the center of the belt (in line with your belly button).  
Slide the measuring tape between your legs.  Select which leg you want to use for measuring and wrap the measuring tape taught around the back of that leg (around the butt check) and then bring it back around to the front back to the center of the belt where you started the measurement.
In essence you should have the measuring tape wrapped fully around one of your legs tautly (but not so tight it restricts blood flow) with the start and end point of the measuring tape being the front center of your belt.
Take the leg strap measurement, and then subtract 15 inches, this should give you the length of leg strap you need for the harness to fit securely but still be comfortable. 

To determine if you require a Deuce or Deuce Magnum product you will need to consider penis girth measurement.

Penis Measurement
With the penis fully erect, wrap the tape measure around the base of the penis one complete time, and where the tape measure crosses over it self, take the measurement and see size chart above for Circumference of Second Hole Opening (For Penis).
