How does an inflatable T-Rex costume stay inflated?

It uses a small, battery-powered fan that continuously blows air into the suit. Elastic bands at the wrists and ankles keep the air from escaping, maintaining its shape.

Can you breathe easily inside the T-Rex costume?

Yes, the fan constantly circulates fresh air from the outside into the suit, making it safe and breathable, though it can get warm.

What should you wear under an inflatable dinosaur costume?

Wear lightweight, breathable clothing like a t-shirt and shorts. Avoid heavy layers, as the polyester fabric traps body heat.

How to put it together

1
Install fresh batteries into the battery pack or connect a fully charged USB power bank.
2
Step into the legs of the deflated T-Rex jumpsuit with your shoes already on.
3
Clip the battery pack securely to your waistband or pocket inside the costume.
4
Slip your arms into the sleeves and pull the costume up over your shoulders.
5
Turn on the fan switch to start the airflow, then carefully zip the costume completely closed to seal the air inside.
6
Adjust the clear viewing window at the neck so it aligns perfectly with your eyes.

Makeup & hair

No makeup or hair styling is required since your entire head and body are fully enclosed inside the inflatable suit.

Tips

Always carry a spare set of AA batteries or a backup power bank to prevent mid-party deflation.
Wear light, moisture-wicking clothes underneath because the polyester material traps heat quickly.
Watch your clearance; the tall head and long tail can easily knock over drinks or decorations.
To sit down, gently guide the tail forward or to the side and slowly lower yourself, letting the air compress.
