Helmet and cheek pad

A helmet comprising:

• a helmet body;
• and
• right and left cheek pads arranged inside the helmet body, as viewed from a wearer of the helmet, wherein the cheek pads each include:
• a first bottom portion including a first outer surface located downward from a lower edge of the helmet body;
• and
• a second bottom portion including a second outer surface located rearward from the first bottom portion, wherein
• the first outer surface and the second outer surface form a wearing opening of the helmet and are negative pressure generating surfaces configured to generate a downforce acting on the helmet by having the first outer surface located downward from the second outer surface, and
• the first bottom portion and the second bottom portion are resilient so as to enlarge the wearing opening when receiving force for enlarging the wearing opening and reduce the wearing opening in size when the force is removed,
• wherein a lower end of the first outer surface projects from the lower edge of the helmet body more greatly than a lower end of the second outer surface;
• wherein the first bottom portion and the second bottom portion are separated by an inclined portion that has an inclined surface angled relative to each of the first outer surface and the second outer surface.
