Why choose a double cock ring over a single one? A single ring grips the shaft only. A double ring adds a second, larger loop that goes behind the testicles. With two anchor points the toy is less likely to roll, twist or slide during sex, and the pressure is shared between shaft and balls. On the Hard-On Double the cock ring measures 1.2 inches across and the ball ring 1.7 inches, and the vibrating bullet sits above them where it can touch a partner.
Hard-On Double: two rings and a bullet in one harness
The Jock Hard-On Double C-Ring is a stretch silicone harness with two rings. A 1.2 inch ring goes around the shaft and a 1.7 inch ring goes around the balls, which gives a more secure hold than a single-ring design. A vibrating bullet sits in the silicone above the shaft, placed to stay in contact with a partner during sex.
The bullet has 9 vibration modes: 3 speeds, from a low hum to a strong buzz, and 6 pulse patterns. One magnetic button on the harness cycles through them. The bullet pops out for use by itself, charges by magnetic USB, and the whole toy is rated IPX6 for the shower.
Best for: For couples who want a vibrating ring that stays put, and for men who like pressure at both the shaft and the balls. Two rings take a little more practice to put on than one, so it suits users who have worn a cock ring before.

How to use
Charge the bullet by magnetic USB and fit it into the harness. Apply water-based lubricant to the inside of both rings. While soft or partly erect, stretch the larger ring and pass the testicles through one at a time, then pull the shaft through the smaller ring. Turn the bullet so it sits on top. Press the magnetic button to start and keep pressing to step through speeds and patterns. As general guidance, wear a cock ring for no more than about 20 to 30 minutes, and remove it at once if anything hurts or goes numb.
Care
- Use water-based lubricant only.
- Wash with warm water and toy cleaner before and after each use; do not boil it or use a dishwasher.
- Pat dry before charging the bullet by magnetic USB.
- Store in a cool, dry place out of direct sunlight.
- Keep it separate from other toys.

Frequently asked questions
What sizes are the two rings?
The cock ring has a 1.2 inch inner diameter and the ball ring a 1.7 inch inner diameter, both measured unstretched. The silicone stretches to go on. The whole harness is 2.7 inches long and 2.2 inches wide.
How is it different from the single Hard-On C-Ring?
The single version has one 1.3 inch ring and an IPX5 rating. This Double adds a ball ring for a firmer hold and is rated IPX6. Both use a removable bullet with 3 speeds, 6 patterns and magnetic USB charging.
Can the bullet be used separately?
Yes. The distributor says the bullet pops out of the harness for stand-alone use during foreplay. It keeps the same nine modes, and it goes back into the silicone when you want to wear the rings.
Can I take it in the shower?
Yes. It carries an IPX6 rating that covers both the harness and the bullet. The distributor describes it as suitable for the shower and for rinsing clean under running water.
How do I change the vibration?
One magnetic button on the harness controls everything. Each press moves to the next of the 3 speeds and then through the 6 pulse patterns. The intensity rises as you press through the speeds.
