  • Fat Boy™ Thin Sheath


    Perfect Fit re-introduces the Fat Boy Thin Sheath now in sharp all new vertical storage packaging. Adds noticeable girth (0.5") to your penis without being too much for your partner to handle. Made of super soft and stretchy SilaSkin, it is designed and proven to give both partners intense, eye-rolling pleasure. 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.

    Safe for use with water-based lubes.

    Wash thoroughly with mild soap and water.

    Not compatible with latex products.

    This product is not a contraceptive or substitute for a condom. Not compatible with latex products. Please store separately.
