No, this isn't about the iconic browser that has a fox logo. But if you're a fan of that, this red fox onesie by Primark suits you best. The red fox is also a nocturnal animal, hence this onesie is perfectly made for slumber. It has a fox head hoodie and a zipper in front.
Size guide: if in doubt take a size up as onesies are much more comfortable with a looser fit.
