Adult Ghostbusters Inflatable Giant Stay Puft Costume

The 100-Foot Terror, Now Wearable

There are few villains in cinematic history as deceptively cheerful — or as catastrophically destructive — as the Stay Puft Marshmallow Man. That grinning sailor hat, those pillowy white folds, that wave that says "hello" while an entire city block trembles beneath enormous marshmallow feet. This officially licensed Ghostbusters inflatable costume brings the beloved giant to life in glorious, puffed-up fashion, making it one of the most recognizable Halloween looks anyone could possibly wear.

Blown Up To Glorious Proportions

Constructed from 100% polyester windbreaker fabric, this billowing bodysuit inflates via a battery-powered fan installed at the back of the right hip, transforming the wearer into a rotund, marshmallow-white behemoth. The fan runs on four AA batteries stored in a conveniently placed inner pocket that also features a clip to secure it directly to clothing inside the suit. Once inflated, the costume faithfully recreates every iconic detail — the navy blue sailor collar, the red neckerchief and hat ribbon, the cheerful wave of one plump arm, and of course that eternally satisfied grin.

Surprisingly Simple To Suit Up

A back zipper makes getting into this massive marshmallow straightforward, while the fully enclosed hands keep the look seamless and polished from wrist to fingertip. Hidden elastic at the ankles tucks neatly beneath attached shoe covers, so no awkward gaps interrupt the illusion of those unmistakable pillowy legs and rounded feet.

Seeing The World Through Puft's Smile

Vision is handled through a mesh-covered viewport discreetly positioned behind the character's iconic open mouth, allowing the wearer to navigate crowds, parties, and trick-or-treat routes without losing sight of the chaos they're causing. Few Halloween costumes command this kind of immediate, crowd-stopping recognition — and fewer still arrive with this much sheer, marshmallow-scented joy.
