SpareParts Deuce Harness - Regular Size B


Deuce from SpareParts is the first harness designed especially for men! Deuce is a brilliant solution that allows you to continue lovemaking in between erections, not to mention an excellent tool for double penetration. 

Two separate holes allow for the penis to extend through one and a toy to extend through the other, so there is no need to skip a beat when pleasuring your partner. An internal pocket holds a vibrator for extra stimulation, and a unique pouch comfortably cradles "the boys". Leg straps lightly cross over the perineum for added pleasure. Comfortable and completely adjustable, it can be worn for extended periods and makes it a great solution for men with erectile dysfunction.

The Top Hole of the Deuce Magnum measures 1.25 inches to 2 inches with an elastic and stretchable O-ring that fits a variety of strap-on dildos and dongs. The Bottom Hole of the Deuce Magnum measures between 2 inches to 2.375 inches designed to accommodate the larger natural girth of the wearer, acting as a soft penis ring.

  • Nylon, Spandex
  • Waist Belt: 35 - 65 in.
  • Leg straps: 14 - 24 in.
  • Upper hole diameter: 1.25 - 2 in.
  • Lower hole diameter: 1.5 - 1.87 in.

The stylish Deuce is comfortable and durable. The adjustable straps ensure it fits the wearer securely and remains snug and in place, providing complete control whatever the position. As the leg straps cross at the perineum, they apply light pressure to the prostate region giving an additional pleasurable feeling. The Deuce has an elastic and stretchy O-ring that expands and contracts to hold a variety of dildos of different shapes and sizes, so each and every experience can be a new and exciting one.

In addition, there is a second hole just below the O-ring that is lined with soft stretchable elastic which is designed to accommodate the natural girth of the wearer. This subtle touch to this unique harness, allows the second opening to act as a soft cock ring creating another pleasurable dimension when using the Deuce. Both openings have two small flaps on the inside of the harness so that the wearer has the choice of having the dildo base against his skin for that more intimate and involved feeling or he can have it covered for a gentler, less abrasive sensation. With the flaps, the wearer can also opt to have his penis inside or outside the pouch. So you can enjoy the Deuce in multiple fun ways!

For an additional vibration, the flaps for the top dildo can accommodate a wireless mini bullet vibrator for that extra sensual stimulation. Vibrating cock rings can also be used with the Deuce™ for a further titillating sensation to the dildo and to the penis. The belt is secured with Velcro and has a second elastic pull feature for locking your product of choice into place. The locking mechanisms on the leg strap allow the wearer to move the sliders into place, whilst the locking teeth of the top slider hold the straps and harness in place so the harness is secure the entire time it is worn. The Deuce can be worn comfortably without having to constantly re-adjust.

The simplicity of the Deuce means it makes it easy to use in 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.

As the Deuce is designed especially for men; the pouch is designed so that it comfortably cups the testicles and penis if desired, without resulting in bunching, chaffing, pinching or binding. It’s also a fantastic choice of harness for men who have erectile dysfunction. The versatility of the Deuce means it can be used with only a dildo or with penis and a toy simultaneously for dual penetration and double the fun.

 Deuce™ is for you?

Start with measuring for the perfect fit.

For Deuce, you will need to consider Belt measurements (hips), Leg measurements (thighs), and penis measurements (girth only) to determine which Deuce will produce the best fit for you or your partner. Follow these simple steps to determine which Deuce™ product will fit you perfectly! To determine if you or your partner is a size A or B, you will need to consider both the Belt and Leg strap measurements.

MEASURING FOR THE BELT: Wrap measuring tape around your hips, where you would wear your belt.  Take the number where the tape measure completes and crosses over itself.  You should add a few (3-4) inches to this measurement for size fluctuation and room for sizing adjustment.  Take the measurement and see the size chart above for Belt and determine which belt would be best.  (You should be able to select a size that is reflective of your pant or belt size.  So if you wear a size 32 in pants, and they fit you securely, you should select the Deuce that best fits 32 inches).


Step one:  To measure which size is best for the wearer; first figure out where you will be wearing it on your hips.  The best way to do this is to put on a regular belt, as this will help you to have a place to start and finish measurement on the next step.

Step two: Next 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 endpoint 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. See size charge above Leg Straps.

DEUCE OR DEUCE MAGNUM: To determine if you or your partner requires 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 itself, take the measurement and see the size chart above for Circumference of Second Hole Opening (For Penis).
