How long do the batteries last in an inflatable dinosaur costume?

A fresh set of four standard AA alkaline batteries will keep the fan running and the costume fully inflated for about 4 hours.

Is it hot inside an inflatable dinosaur costume?

Yes, because the suit is made of non-breathable nylon to hold air, it can get warm. Wearing light, moisture-wicking athletic clothes underneath helps keep you cool.

Can you sit down while wearing an inflatable dinosaur costume?

Yes, but it requires care. Gently compress the air as you sit, ensuring you do not block the fan intake, which must remain uncovered to keep the suit inflated.

How to put it together

1
Put on your lightweight, breathable base layer clothing and comfortable walking shoes.
2
Insert four fresh AA batteries into the costume's battery pack and connect it to the built-in fan.
3
Step into the legs of the dinosaur suit, pulling the elastic cuffs snugly around your ankles or shoes.
4
Slip your arms into the sleeves, ensuring the elastic wrists are tight to prevent air from escaping.
5
Zip up the back of the suit completely and turn on the battery pack switch to start the fan.
6
Stand upright and wait about one to two minutes for the dinosaur suit to fully inflate around you.

Makeup & hair

Since your entire head and face are hidden inside the inflated suit, no makeup or hairstyling is required. If your model has long hair, tie it back in a low bun or ponytail so it does not block your view through the clear plastic window.

Tips

Always carry a spare set of AA batteries in your pocket in case the fan starts to lose power mid-event.
Drink plenty of water beforehand, as the sealed nylon material can trap heat and make you sweat.
Make sure the clear plastic viewing window is clean and positioned directly in front of your eyes before fully zipping up.
Take slow, wide steps to accommodate the wide, air-filled legs and avoid tripping on uneven surfaces.
