What's in the Box

Canary yellow jumpsuit with integrated hood and biohazard symbol chest print
Gas mask with distressed red and black finish
Black elbow-length gloves

This Adult Biohazard Hazmat Costume brings the apocalypse to your next Halloween party with a blood-splattered yellow coverall, gas mask, and full contamination-response setup. The canary yellow jumpsuit features dramatic red and brown blood splatter throughout—heavier on the torso and lower legs—with a bold black biohazard symbol printed front-center.

Lightweight polyester construction keeps you comfortable through long wear, with a front-zip closure running collar to crotch for easy on/off. The integrated hood, elastic wrist and ankle cuffs, and relaxed fit give you freedom of movement whether you're working a haunted house shift or hitting a zombie walk. The gas mask adds instant horror credibility with its red-distressed finish over black base and breathing filter detail.

Perfect For

Halloween Parties & Horror Events: A standout pick for zombie-themed costume parties, apocalypse pub crawls, or haunted attraction staff uniforms—pairs naturally with contaminated scientist or infected medic costumes for couples.

Zombie Walks & Conventions: Instantly recognizable as a contaminated hazmat responder at zombie walk events, horror conventions, or post-apocalyptic cosplay meetups—the blood splatter and gas mask do the heavy lifting.

Themed Parties & Group Costumes: Works solo or as part of a coordinated outbreak response team for work events, pub theme nights, or friend-group costume lineups.

How to Wear It

Pair with black combat boots or work boots to complete the contamination-response look. Add fake blood accents to the gloves or mask for extra horror impact, or carry a prop clipboard and specimen bag for authenticity.

Fit & Sizing

What size should I order?

Check the size chart for chest and height measurements. The jumpsuit runs relaxed through the body with elastic cuffs at wrists and ankles—if you're between sizes and want a fitted look, size down; if you plan to layer warm clothes underneath, size up.

Can I wear regular clothes underneath?

Yes—the lightweight polyester fabric and front-zip design make it easy to wear over a t-shirt and jeans. The elastic cuffs keep sleeves and pant legs secure even with underlayers.

Is the mask breathable for long wear?

The gas mask is a costume prop with open eye pieces and filter detail—it's wearable but not designed for extended comfort. Remove it between photos or haunted house shifts if needed.

Is this suitable for outdoor Halloween events?

Absolutely—the full-body coverage and hood work well for cooler October nights. The blood splatter effect holds up in light rain; avoid heavy downpours to protect the print.

Care: Hand wash cold, hang dry. Avoid bleach to protect the blood splatter print.
