It's a logo for a mask snorkel. It shows only the mask, snorkel and mouth. The mouth is a "C" that is curved upwards and the snorkel is coming out of it to the right. The mask is above the mouth.
This icon is a part of a collection of Snorkel flat icons produced by Icons8. Icons follow the guidelines of iOS, Windows, and Android and are designed by a single designer, guaranteeing the consistent quality.
