Dinosaur Costumes for Adults and Kids

Dinosaur Costumes for Adults and Kids

The Inflatable T-Rex Dinosaur Costume runs on a battery-powered fan that holds the whole suit firm for over four hours, with your own face left open at the front instead of sealed behind a window, and a pair of gloves included in the pack.

Dinosaurs sit alongside our animal costumes and skeleton costumes in the wider costume themes range.

Choose Your Dinosaur

Past the T-Rex, the adult range adds a Velociraptor, a Triceratops, and a fleece onesie with no fan and no batteries. Our kids dinosaur costumes range carries more styles and sizes for children.

Built on the same fan and battery as the T-Rex, the Giant Velociraptor Inflatable Costume adds a built-in pocket for your phone or keys.

Swap the open jaw for three horns and the Triceratops Giant Inflatable Costume does the same job, pairing a high-powered fan with elastic seals at the wrists and ankles so air stays where it should through a full night out.

Fleece instead of air, the Mens Green Dinosaur Onesie Costume is a hooded jumpsuit with felt teeth, back spikes, and an attached tail, sized Medium to XL by chest and height.

How the Fan Keeps It Standing

Our inflatable dinosaurs leave the head free, so your own face stays open at the front: you can talk, eat, and drink without coming out of the costume, and nothing steams up in front of your eyes. The fan runs continuously to keep the costume inflated, rather than a one-time blow up by mouth. Every costume goes through over 30 measurement checks. None of the inflatable dinosaur styles suit children under three, because of the small parts in the fan and battery unit.

Sizing carries down to children as well: the Kids Inflatable T-Rex Dinosaur Costume runs the same fan mechanism in a child-sized suit that closes with hook-and-loop fastening at the front.

Under-threes cannot use the fan and battery pack, so the Kids Green Dinosaur Costume leaves both out: a jumpsuit with an attached hood and a Velcro-release tail, sized for one to four year olds.

Frequently Asked Questions

How much do dinosaur costumes cost?

A toddler jumpsuit is the least expensive option, and a full adult inflatable with a fan and battery pack costs more. The fleece onesie sits in between, since it skips the fan but is a full one-piece build.

How does an inflatable dinosaur costume stay inflated?

A small fan built into the suit runs on four AA batteries, not included, and holds the dinosaur shape continuously, instead of a one-time blow up by mouth. Battery life runs to about four hours on our adult styles.

Can you see and breathe properly in an inflatable dinosaur costume?

Yes. Our inflatable dinosaur costumes leave your own face open at the front rather than sealing you behind a cellophane window, so sight and breathing stay close to normal. Vision softens a little at the edges of the head shape, so take care around curbs, steps, or low light, the same as with any oversized costume head.

What size is an inflatable dinosaur costume?

The adult inflatable styles, T-Rex, Velociraptor, and Triceratops, are one size, built to fit most adults. The kids inflatable T-Rex is also one size, fitting most children. The fleece onesie is sized Medium to XL for adults, and the toddler jumpsuit runs Small to Large for ages one to four.

What goes with a dinosaur costume for a group?

The three adult inflatables are different species, so a group of three can go T-Rex, Velociraptor, and Triceratops without anyone repeating a costume. Our wider animal costume range works for a mixed group, and the kids inflatable T-Rex matches the adult one for a family.

Is a dinosaur costume suitable for young children?

Not the inflatable ones: the fan and battery unit has small parts, which puts them out of reach for under-threes. For a younger child, the Kids Green Dinosaur Costume is a jumpsuit with an attached hood and tail, sized from around age one.
