This isnt really a fursuit, but its still a costume so Ill post it anyways! :)

This is a cosplay of a character from an RPG game called:
OFF, by Mortis Ghost.
The head piece and the hands are based off of foam so they are flexible and can handle a lot of wear and tear. It features a moving jaw as well, with vision out of the mouth. The teeth are also hand sculpted and attached individually!

You can see some WIP gifs that show the jaw movement here:
