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.

Terrible taste, great brand
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
Thorne is a phenomenal company and the only supplements I trust. The reason I rated this so low is the absolutely disgusting flavor. Do yourself a favor and try another option

Flavor is a problem
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
The flavor ……it’s tough. It’s like drinking a sweet TART. Emphasis on tart. No better way to describe . Can’t get past the flavor to make other comments .

Great for recovery
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
Really helps with post work out recovery. I feel noticeably less sore when I take this after a workout. Definitely prefer the lemon flavor over the berry.

Great formula, but desperate for an unflavored option
Flavor Name: Berry, Size: 30 Servings (8.0 Ounce) (Pack of 1)
I’ve been incorporating Thorne’s Amino Complex into my daily stack, and from a nutritional standpoint, it’s hard to beat. The clinical dosing of essential amino acids is exactly what I’m looking for to support my recovery and fitness goals. Thorne is usually my go-to for purity and quality, and this product is no exception when it comes to the actual ingredients. ​However, the flavor profile is a significant drawback. To be blunt: the flavors are just not good. They feel chemically and overly sweet, which makes it a chore to drink rather than a supplement I look forward to. ​I would much prefer an unflavored and unsweetened version. Having the option to just mix the raw powders into water or my own beverage without the unnecessary flavorings and sweeteners would be a game-changer. If you’re sensitive to artificial tastes or just prefer a "cleaner" experience, the current options might be a struggle. ​Pros: ​High-quality amino acid profile. ​Trusted brand with great sourcing. ​Cons: ​Flavors are unpleasant and too sweet. ​No "naked" or unflavored option available.
