We are thrilled to introduce the new Fat Boy™ line of sheaths, which includes our classic Fat Boy™ Thin and the Fat Boy™ Ultra Fat–formerly known as our super popular Fat Boy Sport–plus two new textured models, the Fat Boy™ Checker Plate and Fat Boy™ Micro Rib.

All are packaged in all new vertical storage packaging.  The two newest models, the Checker Plate and Micro Rib, are both designed and proven to give both partners pleasure.The Checker Plate texture is the most stimulating for the receiver, while the Micro Rib texture provides a more gentle stimulation. Both are available in three size options.

Note: We no longer refer to the Fat Boy™ products as "extenders," but instead use the term "sheaths." And, FYI: We invented this category of sex toys! A Little Fat Boy™ History The Fat Boy™ was the first soft stretchy sheath ever conceived. It was born from the desire to have both partners reach orgasm while using an “Extender”. This innovation started an extender revolution, and the industry has aptly called this new concept “Sheaths.” To this day, 10 years after we first made the first sheath, the Fat Boy line is a best seller and continues to be recognized as one of the best sex toys made. Men’s Health named it one of the best sex toys of 2017! What made this possible, was the development of a remarkably soft, silky and stretchy material we call SilaSkin™. The first TPR/Silicone to ever be used in production, this unmatched and seriously sensuous material has become a building block for many other award-winning products by Perfect Fit.

Our ultra-real feeling 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 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 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.

Good quality, smooth feel
I got these briefs so recently that have washed just one pair so far. First off, these are very comfortable, the material is soft & bordering silky, good quality sewing. Wash well and minimal if any shrinkage. They do come a bit wrinkled from the dryer but hey, these are underwear and will go on smoothly. If it were a t-shirt, I would look sloppy. I feel the sizing is accurate. No rolling and these don't announce themselves under clothing. Planning on getting more of these boxers and replacing my old panties.

A little snug on the thighs
Size: Medium, Color: Multicoloured G (5-pack)
Super comfy, soft and thin. For reference, I'm 5'6", 135, athletic build. I bought medium. I almost returned them because I thought they were a bit too snug on my thighs, and my thighs are not large at all. I was concerned about panty lines under snug clothing. But, because they're thin, I figured they would probably stretch, so I kept them. So far, I've only worn them under a night shirt, but they're super comfortable and they dont ride up at all. Very nice, but if your thighs are a little thick, you probably won't like them.

Functional + Sexy
Size: Small, Color: Multicoloured E-(5-pack), Size: Small, Color: Multicoloured E-(5-pack)
Not only do these feel good, my husband can’t keep his hands off me. They fit so good and are soft. I change into these to sleep but also just use them as shorts to wear around the house. They’re comfortable and don’t slide around. I got a size small and I’m 100lbs.

Finally!
Size: X-Large, Color: All Black D (5-pack)
Finally, comfortable underwear that don’t end up giving me a wedgie. I have a round booty and most cuts of underwear end up shifting as I walk and sit. The hem of the underwear comes right under my cheeks and the lightweight material ensures there’s no panty line and no shifting to where I don’t want them! I’m definitely purchasing more.
