Best in the game

I got the Power Flex in 45mm and the Pulse Flex in 40mm, both silicone. The Power flex in 45mm is perfect to wear all day. Stays in place and doesn’t hurt after prolonged time, since it doesn’t have too much stretch the 45mm feels great.The Pulse Flex in 40mm for me is tighter so good for play time but not comfortable enough for all day or prolonged time. The Pulse is a little harder to get on due to the smaller size but it does have a little more stretch than the Power Flex. Love the keyhole design. My balls definitely appreciate it as well compared to traditional round rings. Id recommend the 45mm for most people who want a comfortable fit and the 40mm if you want it real tight!

Very comfortable

The ring was great, loved when I read my USPS informed delivery and it said, "your power flex Cock ring is on its way". Since when is that considered discreet? They have a leak in that department and claim they did not tell the post office what was in the white box. So who did?

How to measure for the perfect fit

Gather Your Supplies. You'll need a piece of string and a ruler to get your measurement. We recommend using a string instead of trying to use a soft tape measure.

Measure. Wrap the string around your penis and behind your balls. Mark the string where it meets. You want the string quite snug. You should be able to just fit a finger between your skin and the string when you're soft. And it should be comfortably tight when you're hard so that you can't fit in a finger. You may want to measure both soft and hard to double-check your size.

Determine Your Size. Measure the distance from the end of the string to the mark.  This is the circumference.  Use the handy table below to get your size.

Circumference Ring Diameter
13.0-14.5cm (5.0-5.75in) 40mm (~1.6in)
14.5-16.5cm (5.75-6.25in) 45mm (~1.8in)
16.5-18.0cm (6.25-7.0in) 50mm (~2.0in)
18.0-19.5cm (7.0-7.75in) 55mm (~2.2in)

Tips For Measuring

  • Most guys are in the 40mm-50mm range.
  • 55mm is a pretty big ring. So if you're not bigger than average, try measuring again and make sure you pull the string tight.
  • If you have a good-fitting round ring, MEASURE ANYWAY. You may find your Primal ring size is 5mm (~.2 in) smaller than your round ring size. Our keyhole shape fits a bit looser than a round ring with the same diameter.
  • Measure twice!  Due to the intimate nature of these rings, we can't accept returns or exchanges.
Remember: Safety first! Do not wear a ring that is too tight, and remove the ring immediately if you feel discomfort, a sensation of coolness, observe any changes in color, bleeding, or feel tingling or numbness. If in doubt, take it off. Men with pre-existing genital conditions or injuries, or those taking anticoagulants should consult their physician prior to use. Cock rings should not be worn for more than 30 minutes, and you should not sleep in a ring.
