The Grubby is made from a lightweight, breathable fabric that is both strong and durable. The Grubby is specifically designed to be slipped on over your child’s clothing and to protect the little one from dirtying up his/her clothes. The Grubby works great in wet and dirty areas, including when it’s raining, giving added protection to clothing underneath, without sacrificing comfort or mobility. Kids can crawl, run, climb, jump, and just be kids without worrying about getting dirty or wet. The Grubby is machine washable and can be used over and over again!
