The Backrooms costumes are already turning up on Spirit Halloween shelves. The official Async hazmat suits, in green and yellow, and a matching gas mask are in stores now, even though they have not appeared on Spirit’s website yet or in every store.
The Three Backrooms Items at Spirit
Three Backrooms pieces have surfaced so far, all built around the Async crew, the hazmat-suited team from the series:
- Green Async Hazmat Suit
- Yellow Async Hazmat Suit
- Async Gas Mask
The two suits carry the crew’s color-coded look, and the gas mask completes the outfit. Spirit’s commercial confirmed the official designs, and the in-store sightings so far line up with those three pieces.
The hooded jumpsuits come in adult sizing, with the gloves included, and the packaging labels them plainly as the Green ASYNC Hazmat Suit and Yellow ASYNC Hazmat Suit.
The Official Async Costume Designs
Spirit first showed the costumes off in a recent commercial, which is where the official designs appeared. The spot said the costumes would be available in the coming weeks.

In-Store Sightings
The hazmats have started popping up in Spirit Halloween stores, and fans are sharing photos of the suits online. They match the look of the Async crew from the series, right down to the color-coded hazmat gear. The gas mask is turning up on pegboards too, tagged as the ASYNC Gas Mask. The fan account Kane Parsons Film Updates has been posting the in-store finds.

Check Your Local Store
The costumes are not listed on Spirit’s website yet, and they are not showing up in every store. They will likely roll out at select locations through the season, so the best move is to check your nearest shop on the Spirit Halloween store locator. We have not seen prices or item numbers posted online, so pricing is store-by-store for now.
The Backrooms Arrives on HBO Max September 25
The Backrooms began online as a series of short horror videos set in an endless maze of empty rooms, and A24 has turned it into a film that arrives on HBO Max on September 25. We covered everything to know about the Backrooms coming to HBO Max. For fans who want to dress as the Async crew this Halloween, the costumes are in stores now, and the best way to find them is to check your local Spirit.
