“Expand your natural lovemaking abilities with this must have male harness. ”

The Deuce™ is the very first harness from SpareParts HardWear™ that is especially designed for men! The Deuce™ is a unique harness which has been created to assist men in prolonging foreplay and as a brilliant alternative to continue love making sessions in between erections, creating further intimacy between partners!

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 a light pressure to the prostate region giving an additional pleasurable feeling. 

The Deuce™ has an elastic and stretchy O-ring which 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 more 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 a multiple of 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 holds 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 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. 

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.

Which size 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 measurement (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.

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 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 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. See size charge above Leg Straps.

To determine if you or your partner requires a Deuce™ or Deuce Magnum™ product you will need to consider penis girth 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).
