Perfect Fit Xact-Fit #18 Silicone Cock Rings 2 Pack 45.5mm

Two Identical #18 Rings With Controlled Stretch for A More Precise Fit Than A Typical One-Size Cock Ring

The Perfect Fit Xact-Fit #18 is for anyone who is tired of cock rings being either vaguely stretchy or completely unforgiving. This pair gives you a defined 45.5 mm internal diameter with just enough silicone flexibility to make fitting easier.

Both rings are exactly the same #18 size, so this is not a sizing sampler. It makes the most sense when you already know that a ring around 45.5 mm is in your preferred range and want two matching rings ready to go.

The plush soft-touch silicone is deliberately not excessively stretchy, helping the ring maintain a more predictable fit than highly elastic TPE while still being easier to handle than rigid metal.

“Once you know your size, having two identical rings beats buying another pack full of sizes you will never use.”

Perfect Fit Xact-Fit #18 Cock Ring Key Features:

✅ 2 Identical #18 Rings: Both rings in the pack are the same Xact-Fit #18 size rather than two different diameters.

✅ 45.5 mm Internal Diameter: Perfect Fit lists the #18 at approximately 45.5 mm internally, giving you a clear starting size instead of a vague one-size label.

✅ 143 mm Internal Circumference: The manufacturer-published circumference for #18 is approximately 143 mm.

✅ Precision Xact-Fit Sizing: The range is built around closely spaced nominal 0.1-inch size steps, making it easier to move up or down without a huge jump in fit.

✅ Controlled Stretch: Xact-Fit silicone is intentionally less elastic than many generic cock rings, helping the individual size retain its meaning once worn.

✅ Soft-Touch Silicone: Plush silicone provides a smooth, flexible alternative to completely rigid metal.

✅ Size Stamped On Each Ring: Both rings are marked #18, so it is easy to identify your preferred Xact-Fit size later.

✅ Strong Silicone Construction: Perfect Fit describes the rings as highly durable while still providing enough flexibility for practical fitting and removal.

✅ Can Be Stacked: The pair can be worn together by experienced users, although stacking increases constriction and should be approached cautiously.

Product Details

Xact-Fit solves a very ordinary problem surprisingly well: most cock ring ranges leave big gaps between sizes. Perfect Fit uses much smaller nominal increments, so if one size feels too loose you do not have to leap straight to something dramatically tighter.

The #18 sits between the #17 and #19 sizes and is published at approximately 45.5 mm internal diameter. Because the silicone has controlled rather than extreme stretch, that measurement remains genuinely useful when choosing your fit.

This pack contains two matching #18 rings. Use one as your regular ring and keep the second as a spare, or explore using both only after you are already comfortable with the pressure from a single ring.

The right fit should feel snug and supportive without pain or excessive restriction. More pressure is not automatically better, particularly with a ring designed around precise sizing.

Best For

Best for someone who has already experimented with cock rings and knows that a diameter around 45.5 mm suits them. You get two copies of the size you actually use rather than paying for an assortment.

It is also a strong middle ground between very stretchy beginner rings and rigid metal. The silicone gives enough during fitting to be forgiving, but not so much that every size starts to feel interchangeable.

Not Ideal For

Not ideal if you have no idea what cock ring size suits you. Both rings are #18, so there is no larger or smaller option in the packet if 45.5 mm turns out to be wrong for your anatomy.

It is also not adjustable once fitted. There is no slider, buckle or quick-release mechanism, so choosing the correct size matters more than it does with a lasso-style ring.

Stacking both rings increases constriction. Start with one and never force a tighter setup simply because a second ring is included.
