You too can now explore the Backrooms in Async style with Spirit Halloween’s new costume lineup based on the hit liminal horror film!
Together with A24, Spirit has brought Kane Parsons‘ Backrooms to life this Halloween with a new collection of officially licensed costumes and accessories inspired by the film’s instantly recognizable Async aesthetic.
From its origins as a viral internet horror phenomenon to A24’s 2026 feature film, Backrooms has become synonymous with eerie “liminal spaces,” mysterious hallways, and an unsettling atmosphere.
For fans ready to enter the Backrooms, the collection includes:
Adult Yellow Async Hazmat Suit Costume ($54.99): Bright yellow jumpsuit with long sleeves, a zipper closure, and matching gloves.
Adult Green Async Hazmat Suit Costume ($54.99): Neon green jumpsuit with long sleeves, a zipper closure, and matching gloves.
Async Gas Mask ($12.99): An officially licensed gas mask with an adjustable elastic strap to complete the Async look.
The collection is available now at Spirit Halloween through Halloween while supplies last.
At least now, when you get lost in there, you can look good doing it.
