My buddy, Eric, and I built two custom T-Rex costumes that have been appearing all over North America with Little Ray's Reptiles. They are a ton of work, but the results create memorable experiences for everyone who sees them.
They are approx. half the size of a real T-Rex and we attempted to make them as realistic as possible. Each suit weighs about 80 lbs. and they come complete with a sound system for a cool T-Rex roar and low growl.
