The Perfect Fit Fat Boy Checker Box Sheath takes the award-winning design of the original Fat Boy and introduces a bold, textured surface for extra sensation. Engineered with Perfect Fit’s signature SilaSkin—a unique blend of TPR and silicone—this sheath is ultra-soft, stretchy, and impressively durable, making it perfect for enhancing intimacy without overwhelming your partner. Designed to increase girth, the Checker Box Sheath also has interior nubs and ribs that add pleasure for the wearer, allowing it to double as a stroker.

For secure, comfortable use, the closed-tip design and supportive loop around the base of the scrotum help keep the sheath in place during play, delivering a gentle tug for added stimulation. This sheath prioritizes comfort and intense shared pleasure, helping both partners reach satisfaction.

The Fit Fat Boy Checker requires an erection for use.
