    Perfect Fit is thrilled to introduce the new Fat Boy™ Micro Rib Sheath in three size options with all new packaging. Like their original Fat Boy™ sheath, but with a new textured surface. Adds noticeable girth without being too much for your partner to handle. Made of super soft and stretchy SilaSkin™, it is 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 the balls during penetration or stroking.

    To calculate your ideal size, measure the top of the penis, from base to tip, while erect.
