Fat Boy™ - Rethinking Cock Sheaths

Note: We now call the Fat Boy™ series “sheaths” and no longer using the term “extender.” Perfect Fit Brand invented the cock sheath and the Fat Boy™ line continues to be one of our best-selling series.

With our Fat Boy™ sheath you can add impressive girth to your cock. Our ultra-real feeling, super soft and stretchy cock sheaths are designed to give both partners intense, eye-rolling pleasure. For the receiving partner, the Fat Boy™ adds girth, while for the wearer, with its interior nubs and ribs, it also acts as a stroker.

The feedback from the tens of thousands of Fat Boy™ customers is consistent: Women are crazy for the orgasm-triggering stimulation from the added girth. Men dig the stroker action with or without a partner. Women also like it over the hand as a manual masturbator. And anal bottoms enjoy the thrill of taking a daringly massive, yet remarkably comfortable cock. (Scroll to read customer reviews.) 

The Fat Boy™ is made of SilaSkin™– our own velvety proprietary silicone/TPR material–and designed to please both partners equally.

The Fat Boy™ is extremely comfortable, surprisingly easy to get on and off and stays in place thanks to its closed tip. A thick loop that wraps around the base of the scrotum, which gives a pleasurable tug to a man’s balls during penetration or stroking. 

And though it may look intimidating–even kinky–when you first show it off, because it is soft and spongy, The Fat Boy™ actually adds a fun bonus cushioning effect for those who like to get a little rough and wild. 

About the Fat Boy™ Sport, UK-based sex and relationship coach Rachael McCoy said, “We both actually loved it! Even though it was a bit naughty that my man’s cock was so massive, it felt really, really good!” Check out her video review below or on our Erotic Intent blog at "Rachael McCoy of Inspiring Sexuality Gleefully Reviews The Fat Boy™ Sport."  

The Fat Boy™ is available in four models: two adding a girth of 1” and two adding ½” to ¾”, each available in two lengths. We recommend starting with one of our Fat Boy™ Thin
