Narwhals are the unicorns of the sea. Maybe a bit more chubby than their imaginary brethren, but whimsical and adorable, nonetheless. With impressive tusks that can grow up to 10 feet, Narwhals are magnificent animals. They are excellent swimmers, too, and can dive for as far as a mile into the ocean. They live in cold waters, but never really feel the chill. And, neither will you, with this Narwhal Onesie. The thick, plush material will keep you warm, no matter the outside temperature. Not to mention, you’ll look like a Narwhal - deceptively cute, yet mighty.
