MUST HAVE !!! Watch Video Cutest and so fun EVEN I Love mine !!!! We will get a lot of use out of these. I NEVER WRITE REVIEWS !!! BUT IVe GOT TO TELL YOU. THIS is ONE OF THE BEST ITEMS Ive ever gotten!!! I Absolutely LOve them So easyTO USE with MY 3 yr old Grandson. I told him I have a Surprise for you. We’re going to ride Dinosaurs just you and Nae Nae ( Grandma ) WHAT DO YOU THINK ??? And HE WAS SO EXCITED. I pulled them out and he stepped in and took off SO EASY !!! Rolls up to store we even played in the RAIN drys quick. I think I will add some straps to go over his shoulder as I bought the one for 4-6 so we could use longer. Then also got one for me. 🤣 I do Everything with him. I tell him I’m his Crazy Nae Nae ( Grandma ) lol. The Dinosaurs are nicely made not that fabric that’s easy to rip these are like nylon like a kite material and sewn together. Easy to put on and take off light weight like a pair of pants . Very colorful. Has little battery operated fans inside to blow up. On adult ones the fans could be a little larger for size of dinosaur cause doest stay as inflated as smaller ones. But works fine. YES I WOULD RECOMMEND TO EVERYONE. I GOT THESE AS A PLAYTIME TOY NOT HALLOWEEN. BUT COULD USE FOR Whatever. Dont miss out on ALL THE FUN. 🦕🦖🦕💙🦖💙. Get yours today. ... show more

    • Crowd stopper !!
Size: 2-3YRS,With Hat
This kids inflatable dinosaur Halloween costume is a total hit! Super easy to put on and inflate, and the design is adorable — my kid got tons of compliments. The fan runs quietly and keeps the costume fully inflated throughout trick-or-treating. It’s lightweight and roomy enough to layer clothes underneath if it’s chilly. Just make sure to bring extra batteries for the blower. Great quality and big fun for Halloween! ... show more

This inflatable ride-on T-Rex costume was awesome! My son wore it for Halloween and even won first place in a costume contest. It operated really well, stayed inflated, and was easy to use. The only downside is that it didn’t come with a battery, but once we had one, it worked perfectly. Totally worth it and a big crowd-pleaser! ... show more

    • Best little Dino costume ever! Best little Dino costume ever!
Size: 2-3YRS,With Hat
Review Image by Madi Wilhelm
My daughter refused to take this off for a solid 3 hours, & it wasn’t even Halloween! The quality is great for the money & comfortable enough to where she can wear it & still be having fun & running around. It has air that circulates through it so it doesn’t get too warm while wearing it. It’s durable enough to where we could use it for my son next year as well. The battery life is pretty good on it too, we just used 4 double A batteries & it was on for almost 5 hours in total & still going strong. Everybody thought she was so cute in her little Dino costume & she even won the costume award. ... show more

Review Image by Kitz
Very pleased with this cute costume. Looks like the quality could last another couple halloweens, but that’s it. Fit my 4 year old perfectly and easy enough to get on. We went trick or treating for about an hour and a half and the batteries didn’t run out. (I did bring extra just in case). I paid about $30 for this and feel like $20 would have been a better price. So, not sure about the value for money. Exactly as pictured, stayed blown up pretty well. My son kept feeling like it was falling down, so would keep holding onto it. next time I would get suspenders or something for him ... show more

Size: 4-6YRS,With Hat
This is a must for any child. My grandson loves it. I bought it bigger so he will have it for a while. It still looks great on him he can run with it on. The quality is great

    • Perfect for my T-Rex loving toddler
Size: 2-3YRS,With Hat
I happened upon this and I am sooo very glad I did! Not only is it absolutely adorable, my toddler LOVES it! I did debate between sizes and am very glad I went with the 2-3 year size. My son is 3 and there is a little room to grow. It looks like it'll hold up too...when trying it on (and refusing to take it off lol) he took a couple of tumbles and I saw no issues. The battery pack it a little inconvenient but I appreciate that it makes it a little more 'toddler proof.' The price point of $30 makes it even better! Very happy with this costume!!! ... show more
