Speed and Comfort

If you are as old as us, you likely remember playing Sonic the Hedgehog as a kid. It was quite the experience. Blowing into that dusty cartridge, putting it into your SEGA, and hearing that iconic introduction was the best. What about the gameplay? Sonic was the fastest dude around back then and probably still holds the record for the speediest video game character. Thank goodness Sonic was so cool—we couldn't take our eyes off him (as hard as it was).

Okay, we could keep gushing over Sonic, but we figure you have other things to do this year. If you love Sonic as much as we do, and are considering speeding around in costume onesie, check out this Adult Sonic the Hedgehog Cosplay Union Suit. It's the best way to show love to the remarkable character, whether you are going to bed or wearing the Sonic union suit at the next cosplay convention.

Product Details

The officially licensed Sonic onesie features the classic blue and tan colors of our favorite high-speed hedgehog. The fleece union suit also has a handy zipper down the center front of the costume for speedy changes. The best part of the costume has to be the hood, with filled quills on the back, and Sonic's embroidered eyes. If you need a Sonic outfit this Halloween (or whenever, really), make sure you pick up this Adult Sonic the Hedgehog Cosplay Union Suit.

    Many times I cannot find adult costumes of my interests, let alone in big sizes. I love Sonic, I was so excited to find this. I am soo happy with this costume. I was worried it might be tight, but it's made more like a kigurumi with lots of room, and it fits me perfectly. It's super soft, not too heavy that it would make me sweat, no itchy parts, and seems like it's made really well. Doesn't bother any of my sensory issues! I love it so much and I'm so happy with it! I'm so excited to wear it on Halloween and I'll probably wear it as pajamas too because it's so comfy! :D
    Bottom Line Yes, I would recommend this to a friend.
