PerfectFit Fat Boy 4.0 Cock Sleeve

Not every size-up needs to be dramatic. The PerfectFit Fat Boy 4.0 Cock Sleeve takes a “just right” approach – adding a modest 0.5 inches of girth over a 4 inch sheath length, so the sensation feels noticeably fuller without being overwhelming. It’s a smart starting point for anyone new to sheaths, or for partners who prefer a gentler step up in size.

The built-in scrotum loop keeps the sleeve firmly in place during solo or partnered play, and delivers a pleasurable tug with every stroke or thrust. Putting it on and taking it off is surprisingly straightforward, so there’s no fumbling around when you’d rather be doing other things.

Made from SilaSkin – a proprietary latex-free material – the sleeve has a velvety texture that closely mimics skin. It stretches and flexes to fit a wide range of sizes while maintaining that ultra-real feel. Safe to use with water-based lubricants, and a thorough wash with mild soap and water is all it takes to keep it clean.

Soft, stretchy, and built for both of you

The SilaSkin material is what sets this sleeve apart. Its superior flexibility means it conforms comfortably rather than feeling rigid or restrictive, and the clear finish keeps things looking natural. Whether you’re using it as a masturbator or incorporating it into partnered play – including anal sex – the added girth and scrotum loop work together to heighten sensation on both ends.
