Perfect Fit Xact-Fit #16 Silicone Cock Rings 2 Pack 40.5mm

Two Matching 40.5mm Rings For A Snug, Defined Fit Without The Rigidity Of Metal

The Perfect Fit Xact-Fit #16 is made for anyone who wants their cock ring size to mean something. Instead of relying on a generic stretchy ring, you get a precisely sized 40.5 mm opening and silicone designed to hold its shape without feeling like rigid hardware.

Both rings in this pack are identical #16 models, giving you two of the same fit rather than a mixed assortment. The plush soft-touch silicone has controlled stretch, making it easier to slip into position while maintaining a snug, supportive feel.

Each ring is stamped with its size, so once you know #16 works for you, there is no second-guessing which one to reach for.

“Because finding your favourite fit should end the guessing game, not start another one.”

Perfect Fit Xact-Fit #16 Cock Ring Key Features:

✅ Two Identical #16 Rings: Both rings have the same 40.5 mm internal diameter, making this a practical pack for anyone who already knows their preferred size.

✅ Precision 40.5 mm Fit: A clearly defined internal diameter gives you a more useful sizing reference than a vague one-size-fits-most label.

✅ 127 mm Internal Circumference: The published circumference provides another way to compare the ring with your measurements before choosing a size.

✅ Controlled Silicone Stretch: The material flexes enough for fitting and removal without the extreme elasticity of softer generic rings.

✅ Plush Soft-Touch Silicone: Smooth premium silicone gives the rings a softer feel against the skin while maintaining a firm, substantial structure.

✅ Part Of The Xact-Fit Sizing System: The wider range uses approximately 2.5 mm increments between neighbouring sizes, making it easier to fine-tune your fit.

✅ Size Stamped On Each Ring: Both rings are marked #16, so identifying your preferred size is straightforward.

✅ Strong, Durable Construction: Perfect Fit designed the silicone to resist excessive stretching while retaining enough flexibility for practical everyday handling.

✅ Stackable Design: Perfect Fit allows rings to be combined, giving experienced users another positioning option, although wearing two increases constriction.

Product Details

The Xact-Fit system takes a more considered approach to cock ring sizing. Rather than creating a handful of broadly sized rings and hoping the silicone stretches enough, Perfect Fit offers a range of closely spaced internal diameters.

Size #16 measures approximately 40.5 mm internally, placing it between #15 at 38 mm and #17 at 43 mm. That smaller step can make a meaningful difference when one ring feels loose and the next feels too restrictive.

The silicone has a deliberate balance of strength and flexibility. It is easier to stretch into position than a rigid metal ring, but it does not rely on extreme elasticity to compensate for unsuitable sizing.

This particular pack contains two matching #16 rings. You can use one and keep the other as a spare, making it especially useful when you have already found your preferred fit within the Xact-Fit range.

Best For

Best for someone who already knows that a cock ring with an internal diameter around 40.5 mm works comfortably for their anatomy. Rather than purchasing another mixed-size kit, you get two matching rings in the size you actually want.

It is also a particularly useful option for someone who has tried the larger #17 and found its 43 mm opening a little too roomy. Moving down to #16 reduces the starting diameter by approximately 2.5 mm without making a dramatic jump between sizes.

The controlled-stretch silicone also suits people who want a more predictable fit than an ultra-stretchy ring but are not interested in the rigidity of metal.

Not Ideal For

Not ideal if you are completely new to cock rings and have no idea what size suits you. Both rings are identical, so there is no larger or smaller alternative included if 40.5 mm is not comfortable.

It is also not the best choice if you prefer maximum stretch or adjustable tension. Xact-Fit rings are designed around specific starting diameters, with no buckle, slider or quick-release mechanism.

If you already find #16 uncomfortably tight, the solution is a larger size rather than forcing the silicone to stretch further. The ring should provide comfortable constriction, never pain or excessive pressure.
