Description:

We are thrilled to re-introduce the new Fat Boy(TM) Thin Sheath now in sharp all new vertical storage packaging.Adds noticeable girth to your cock without being too much for your partner to handle. Made of super soft and stretchy SilaSkin(TM), it is designed and proven to give both partners intense, eye-rolling pleasure. The Fat Boy(TM) 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.

Product Details:

  • Materials: SilaSkin™ provides softness & stretch.
  • Adds .5” girth – “just enough” for your partner’s pleasure.
  • The scrotum loop gives a pleasurable tug while stroking or penetrating.
  • Surprisingly easy to put on and take off.
  • Ultra-real feel for intense, eye-rolling pleasure.

Here’s how it works:

Water-based lubricants can dry out or become tacky over time, especially during longer sessions. That’s because the water in the formula slowly evaporates with friction and exposure to air. Instead of reapplying more lube, just add a few drops of water to reactivate the original slipperiness. It instantly restores the glide and smooth feel—no mess, no waste.

Pro tip: Keep a small cup of water or a spray bottle nearby during play. A light sprinkle or mist is usually all it takes to bring your lube back to life.

Nice addition

The sleeve fits well and my wife enjoys the added girth. It’s super soft.

The best feeling

Hands down best feeling on the market. Just make sure to take care of it.

Worked as described

Worked as described but did not hold up as long as I would have liked

Works good

This sheath works best if you have a solid erection that you can maintain. The internal nubs provide needed stimulation, and I don't understand why all sheaths don't include this design.

Comfortable for the wife

This is made from a soft stretchy material, that is much more comfortable for the wife, than the more plastic feeling sheaths that are out on the market.
