7. A helmet kit comprising:

a helmet that includes an outer shell and an inner base material, the outer shell overlying the inner base material, the outer shell of the helmet includes a layer that is materially distinct and different from the inner base material of the helmet, wherein the outer shell and the inner base material define through-holes that extend through the outer shell and the inner base material of the helmet; and a removable helmet cover designed to overly at least a portion of the outer shell of the helmet and cover one or more of said through-holes, the removable helmet cover having an inwardly-faced surface that corresponds in shape to an outer surface of the outer shell of said helmet, the helmet cover including a dome with an outer edge, wherein the helmet cover further includes at least two engaging members including a first engaging member and a second engaging member extending along an outermost portion of the outer edge of the dome, wherein each of the first engaging member and the second engaging member includes an inwardly-extending flange that extends inwardly to a center of the dome, the inwardly-extending flange being defined by the most distal portion of the outer edge of the dome, wherein the first engaging member and the second engaging member cooperate with each other to releasably and repeatedly couple the helmet cover to the helmet by each of the first engaging member and the second engaging member engaging a corresponding rim portion of said helmet and fixing the helmet cover to the helmet by a resilient snap-fit lock, and wherein the dome, the outer edge, the first engaging member, and the second engaging member of the helmet cover are manufactured of a single material to form said resilient snap-fit lock onto a dome shape of said helmet.

8. A removable helmet cover comprising: a dome designed to cover at least a portion of a surface of a helmet, the helmet including an outer shell that overlies an inner base material of the helmet, the outer shell of the helmet being a layer that is materially distinct and different from the inner base material of the helmet; a first engaging member designed to engage a first rim portion of the helmet, the first engaging member being located at a first outermost section of an outer edge of the dome; and a second engaging member designed to engage a second rim portion of the helmet, the second engaging member being located at a second outermost section of the outer edge of the dome, wherein each of the first engaging member and the second engaging member includes an inwardly-extending flange that extends inwardly to a center of the dome, each of the inwardly-extending flanges being defined by the most distal portion of the outer edge of the dome, wherein the first engaging member and the second engaging member are designed to cooperate with each other to releasably and repeatedly fix the helmet cover to the helmet by the first engaging member engaging the first rim portion of said helmet and the second engaging member engaging the second rim portion of said helmet and the first engaging member and the second engaging member fixing the helmet cover to the helmet by a resilient snap-fit lock, and wherein the dome, the outer edge, the first engaging member, and the second engaging member of the helmet cover are manufactured of a single material to form said resilient snap-fit lock onto a dome shape of said helmet.

9. The removable helmet cover according to claim 8 , wherein the first section of the outer edge of the dome is opposite from the second section of the outer edge of the dome, the first engaging member being arranged opposite from the second engaging member along the outer edge of the dome of said helmet cover.

10. The removable helmet cover according to claim 8 , wherein the dome of said helmet cover comprises a front portion and a rear portion, and

at least a section of the outer edge of each of the front portion and the rear portion does not include engaging members.

11. The removable helmet cover according to claim 8 , wherein the dome of said helmet cover defines a concavity, the first engaging member defines the first flange section that extends in a first inward direction of the concavity, and the second engaging member defines the second flange section that extends in a second inward direction of the concavity.
