We've got the best thing that ever happened to your penis, and it's not Viagra. Level up your love game with the Perfect Fit "Fat Boy" Ultra Fat Penis Sheath. First and foremost, this soft extension will instantly add length and noticeable girth to your penis, giving your partner more sensation where it really counts. And, it feels GREAT for you too!

Worried about what your lover will think? Relax, Jack. Not only will you LOOK well-hung, you'll feel like it too with Fat Boy's addictively soft and perfectly natural design. And when your partner isn't around, the extension does double-duty as a stroker par excellence. A soft center and stimulating ribs will ensure an explosive finish every time.

The Fat Boy is made of Silaskin, a perfect mix of Silicone and TPR which gives it an incredible stretch factor, and makes it one of our most popular sex toys for men. The secure design insures it won't slip or shift, even during those extra wild sex sessions. It will also give a pleasing tug on your balls while having sex.

And, this stroker pleases EVERYBODY! 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. 

Fat Boy Sleeves are safe to use with all lubes, including Silicone, Hybrid and Water-Based formulas. Clean-up is quick and easy using warm soapy water and a good rinse. Store dry away from other soft sex toys.

Perfect Fit "Fat Boy" Penis Sleeve Key Features:

  • The iconic Fat Boy is extremely comfortable, surprisingly easy to get on and off and stays in place thanks to its closed tip and 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.
  • The Original Fat Boy Ultra Fat- formerly known as our super popular Fat Boy Sport, this super-fatty adds an impressive 1" girth to your cock! Smooth outside, rippled on the inside inside. 
  • The Original Fat Boy Thin - Adds noticeable girth (.5") to your cock without being too much for your partner to handle. Smooth outside, rippled on the inside inside. 
  • The Fat Boy Micro Textured - Like our original Fat Boy cock sheath, but with a new textured surface for mutually explosive sensations. Adds 0.7" girth.
  • The Fat Boy Checkered Plate - The most textured Fat Boy of them all, delivers potent sensations and wild stimulation to your partner. Adds 0.7" girth.
  • All Fat Boy Sheaths are made from high-quality TPR/Silicone, making them soft, durable, and skin-safe, as well as Phthalates and Latex free. 
  • Product Note: The soft, porous and flexible nature of this product makes it unsuitable for men without an erection.
  • Sheaths should never ever be used a contraceptive or a condom substitute.

Perfect Fit Fat Boy Reviews:

"With a little lube, the Fat Boy slips on just like a condom. No need to make a big deal out of it. That is until your partner feels that added girth and plethora of sensational ribs. The inner texture and flexibility also make this suitable for solo masturbation." -

    Absolutely the best

    Posted by Spider on Dec 7th 2021

    My wife and I used the original for 2 years before we broke it, and we put that thing through the ringer. Ended up buying a cheap knock off from a sex shop and it was not only hard rigid rubber but the strap broke immediately. It looks to me like the a lot of these types of products are made for guys who can't get it up at all, so they are hard but that's not my issue at all. (Just want to be thicker.) We love this one because it's soft (like a really thick condom) and you can even turn it inside out for a different feel. Most importantly, she can't get enough of it!

    My wife and I have gone through 3 of these. Loved the original ultra fat sport but not as satisfied with the newer version. Please bring back the original.
