Perfect Fit Xact-Fit Large Silicone Cock Ring 3 Piece Kit

Three Closely Spaced Sizes Take The Guesswork Out Of Finding A Cock Ring That Is Actually Snug Without Being Too Tight

Cock ring sizing can be annoyingly imprecise. One ring feels loose, the next feels like it skipped three sizes overnight. Perfect Fit created Xact-Fit to close those gaps with rings sized in much smaller increments.

This Large 3 Piece Kit includes sizes #17, #18 and #19, giving you internal diameters of approximately 43 mm, 45.5 mm and 48 mm. Each step is only around 2.5 mm apart, so you can fine-tune the fit instead of settling for “close enough”.

Soft-touch silicone provides firm support with a little stretch, while each ring is clearly stamped with its size so once you find your favourite, there is no detective work next time.

“Three close sizes, one simple goal: find the ring that feels properly snug instead of almost right.”

Perfect Fit Xact-Fit Large Silicone Cock Ring Kit Main Features:

✅ 3 Precision Sizes: The Large kit includes #17, #18 and #19, giving you three closely spaced diameters rather than one generic fit.

✅ Approx. 2.5 mm Size Increments: Each ring increases by only around 0.1 inch, making it easier to fine-tune constriction without a huge jump between sizes.

✅ Size #17: Approx. 43 mm internal diameter with a circumference of approximately 135 mm.

✅ Size #18: Approx. 45.5 mm internal diameter with a circumference of approximately 143 mm.

✅ Size #19: Approx. 48 mm internal diameter with a circumference of approximately 151 mm.

✅ Soft-Touch Silicone: Plush silicone feels smooth against the skin while remaining firm enough to provide useful support.

✅ Controlled Stretch: Xact-Fit rings are intentionally not excessively stretchy, giving them a more defined fit while remaining easier to put on and remove than rigid metal.

✅ Size Stamped On Each Ring: Every ring is marked with its Xact-Fit size so you can immediately tell which one you are reaching for.

✅ Stackable Design: Perfect Fit allows the rings to be combined for experienced users who want to explore a different fit or pressure profile.

Product Details

The clever part of Xact-Fit is not complicated technology. It is simply better sizing. Traditional cock ring ranges can leave large gaps between diameters, which makes finding a comfortable amount of constriction harder than it needs to be.

This kit gives you three consecutive sizes. #19 is the largest at approximately 48 mm, #18 sits in the middle at 45.5 mm, and #17 is the snugger 43 mm option.

If you are unsure which size suits you, starting with the largest ring is the more cautious approach. It should feel secure and supportive without causing pain, numbness or excessive pressure. Move smaller only if the larger ring genuinely feels too loose.

The silicone has some flexibility, but these are intentionally firmer than highly elastic novelty rings. That balance is what lets the sizing system actually matter rather than having every ring simply stretch to the same vague fit.

Best For

Best for anyone who has tried cock rings before and found themselves stuck between “too loose” and “too tight”. The small 2.5 mm jumps between sizes make this set particularly useful when precise fit matters more than flashy features.

It is also an excellent move into more structured cock rings if rigid metal feels too unforgiving. You still get a clearly defined size and firmer hold, but with enough silicone flexibility to make fitting and removal more approachable.

Not Ideal For

Not ideal if you want a completely adjustable cock ring with a slider or quick-release mechanism. These are fixed-size silicone rings, so choosing the right diameter is part of the experience.

This particular Large kit also will not suit every body. If all three rings feel clearly too loose or too tight, the answer is a different Xact-Fit size range rather than forcing one of these to work.

Stacking rings creates additional constriction and should only be explored once you already know how a single ring feels on your body. Never treat stronger pressure as automatically better.
