Perfect Fit Xact-Fit #17 Silicone Cock Rings 2 Pack 43mm

Two Identical 43mm Rings With Controlled Stretch For A More Precise Fit Than A Generic One-Size Cock Ring

The Perfect Fit Xact-Fit #17 is for anyone who has moved past guessing and already knows that a cock ring around 43 mm sits in their preferred range.

Both rings in this pack are identical #17 models, each with an approximately 43 mm internal diameter and 135 mm internal circumference. The soft-touch silicone has enough flexibility to make fitting easier than rigid metal while keeping the sizing meaningful.

Each ring is stamped with its size, so once #17 becomes your go-to fit there is no rummaging through a drawer trying to remember which ring was the good one.

“Know that 43 mm works for you? This pack gives you two of the same fit instead of another collection of rings you may never use.”

Perfect Fit Xact-Fit #17 Cock Ring Key Features:

✅ 2 Identical #17 Rings: Both cock rings are the same Xact-Fit #17 size rather than a graduated pair.

✅ 43 mm Internal Diameter: Each ring measures approximately 43 mm, or 1.7 inches, across internally before stretching.

✅ 135 mm Internal Circumference: The corresponding unstretched internal circumference is approximately 135 mm, or 5.3 inches.

✅ Precision Xact-Fit System: Perfect Fit offers the wider range in nominal 0.1-inch size increments, allowing much finer sizing adjustments than many traditional cock ring ranges.

✅ Controlled Silicone Stretch: The rings flex enough to help with fitting and removal without relying on the extreme elasticity of a generic one-size ring.

✅ Plush Soft-Touch Silicone: Smooth premium silicone provides a softer alternative to completely rigid metal while retaining a substantial feel.

✅ Size Stamped On Each Ring: Both rings are clearly marked #17 for quick identification.

✅ Strong Construction: Perfect Fit describes the Xact-Fit silicone as extremely strong while remaining flexible enough for practical use.

✅ Stackable For Experienced Users: The two rings can be combined if desired, although wearing both increases constriction and should only be explored after you already know how one feels.

Product Details

The clever part of Xact-Fit is not flashy technology. It is simply much more deliberate sizing. Rather than making a handful of rings with large jumps between them, Perfect Fit built a wider range with nominal 0.1-inch steps.

Size #17 corresponds to an approximately 43 mm internal diameter. It sits between #16 at around 40.5 mm and #18 at around 45.5 mm, so moving one Xact-Fit size changes the starting diameter by only about 2.5 mm.

This particular pack contains two copies of #17. There is no larger or smaller backup size inside, which makes it most useful once you already know that 43 mm works for your anatomy.

The silicone gives during fitting, but these are not intended to behave like highly elastic TPE rings. That more controlled stretch is what makes the numbered sizing genuinely useful.

Best For

Best for someone who has already tried cock rings and knows that approximately 43 mm is a comfortable starting diameter. Instead of buying another mixed-size kit, you get two copies of the size you actually use.

It is also a strong choice if you like the predictability of a defined ring size but find rigid metal too unforgiving. Xact-Fit sits neatly between very stretchy beginner rings and fully rigid hardware.

Not Ideal For

Not ideal if you are still discovering your preferred cock ring size. Because both rings are #17, there is no alternative diameter in the pack if 43 mm turns out to be too tight or too loose.

It is also not an adjustable ring. There is no slider, buckle or quick-release mechanism, so correct sizing matters more than it does with a lasso-style design.

Wearing both rings together creates greater constriction than using one. Start with a single ring and never assume that more pressure will automatically create a better experience.
