We are thrilled to re-introduce the new Fat Boy™ Thin Sheath now in sharp all new vertical storage packaging.
The fat boy thin sheath slides on like a second skin, and suddenly every stroke carries more weight—literally. Your partner's breath catches as that extra half-inch of girth fills them completely, stretching in all the right ways. The SilaSkin™ material moves with you, soft enough to feel natural but firm enough to deliver that noticeable enhancement both of you crave.
The closed tip design and thick scrotum loop keep everything locked in place, even when things get intense. No slipping, no adjusting—just consistent girth enhancement that stays put through every thrust and grind. Available in 5.5" and 6.5" lengths, this stretchy material adapts to your size while adding exactly 0.5" of girth that transforms the entire experience.
It's the kind of enhancement that doesn't just change how you feel—it changes how your partner responds, arching into every movement with a hunger that wasn't there before. Water lube safe and phthalate-free, the fat boy thin sheath delivers reliable pleasure without compromise. When the moment builds to that final release, you'll both feel the difference this simple addition makes.
Apply water-based lubricant to both yourself and the inside of the sheath before putting it on—the extra slickness makes application smoother and enhances the sensation for both partners once you're moving together.
