PRODUCT DETAILS
What's in the Box
- White biohazard jumpsuit with printed toxic slime effects and damage marks
- Integrated hood with elastic face opening
- Attached foot covers
- Black fabric gas mask with biohazard symbol
This Kids Zombie Scientist Costume turns Halloween into a post-apocalyptic survival scene — white hazmat jumpsuit printed with dripping yellow-green slime, torn patches, and contamination marks, plus a black gas mask with biohazard symbol. Full-body coverage from hood to foot covers, ready to wear straight out of the bag.
The standout is the printed graphics: toxic waste dripping down the chest, pink and red injury patches on the arms, and gray distressing that looks like your kid crawled through a contaminated lab. Elastic cuffs at wrists and ankles keep the suit secure, and the lightweight polyester fabric won't overheat during trick-or-treat rounds. The gas mask straps on with elastic and stays put.
Perfect For
Halloween & Horror Parties: A natural pick for zombie walks, haunted house events, or any scary costume party where contaminated scientist vibes win.
Apocalypse-Themed Events: Great for post-apocalyptic dress-up days, science-gone-wrong school projects, or any event where biohazard gear fits the brief.
Dress-Up Play at Home: Works for imaginative play — outbreak survivor, hazmat investigator, or mad scientist character games in the backyard.
How to Wear It
Pair with sturdy sneakers or gumboots (the foot covers go over shoes). Skip the gas mask indoors if breathing feels stuffy — the jumpsuit alone still reads as hazmat worker. Add a toy syringe or clipboard for extra lab-tech detail.
Parent FAQs
Q: What size should I order?
Check the size chart for chest and height measurements. The jumpsuit runs true to size with a bit of room for layering underneath. The elastic cuffs adjust to fit different wrist and ankle widths.
Q: Can they wear this over regular clothes?
Yes — the jumpsuit goes on over a t-shirt and leggings or trackies. Handy if it's a cold October night or if you're heading to an indoor party with heating cranked up.
Q: How do I wash this?
Hand wash cold and hang to dry. The printed graphics are screen-transferred, so avoid hot water or the dryer to keep the slime effects from peeling. Spot-clean the gas mask with a damp cloth.
Q: Is this suitable for younger kids who might find it scary?
The costume is horror-themed with contamination and injury graphics — best for kids who love spooky dress-up and aren't easily frightened. If your child prefers gentler costumes, this one's probably too intense.
Care: Hand wash cold, hang dry. Spot-clean gas mask.
