Amazon.com: Customer reviews: Rubies Adult The Original Inflatable T-REX Dinosaur Costume, T-Rex, Standard

I have just tried it on inside so far but seems great. When zipped up before turning on the pump, it seems like it might be claustrophobic but it isn’t at all when you use the pump. FYI the pump is just this little lightweight square with a plastic belt clip connected to it, so it’s pretty easy to clip onto something you’re wearing. Once you zip up and then turn on the pump, it takes maybe 1-2 minutes if that (maybe less than a minute) to fill up. I’m 5’9” and I can put my head at either of the two areas with the clear plastic in order to look out (both around the dinosaur’s neck area). The head and mouth of the dinosaur are above my head completely so it’s nice and airy in there when the pump is going, and it’s even cool inside the dinosaur with the air going. Disclaimer - I haven’t run around in it so I don’t know if that will hold up. The dinosaur arms are pretty short but I think that’s the nature of the t-Rex - it seems like it’d be risky to try to pull your hands/arms up over your shoulders because I just don’t think there’s enough fabric there to allow that without possibly ripping the costume. The dinosaur legs came basically all the way down to my feet. There are holes in the feet, so the costume cinches around your ankles like cinched sweatpants would, and then the dinosaur feet basically overlay your shoes (the dinosaur feet are big enough that they completely cover your shoes so you really wouldn’t see what shoes someone had on). Your shoes then are completely outside of the costume, but everything else is in the costume except your hands and maybe a little part of your wrists/arms, but the costume comes with gloves for your hands. It’s a hilarious and awesome looking costume. I think someone 6’ or so would still probably be able to see through the top of the 2 areas with the clear plastic. Anything higher, you might still be able to fit in the open, airy head part of the dinosaur, but you’d have to scrunch to be able to look out of the plastic I think.
