The mask includes a mask module. The mask module includes an exterior surface and an interior surface. The mask module is sized and shaped to cover a portion of the face. A head module engages the mask module. The head module is configured to engage at least a portion of a user's head. ## Claims ### Claim 1 A mask for protecting a head with a face having a nose, mouth, and chin, comprising: a mask module formed of a material, wherein the mask module comprises an exterior surface and an interior surface, the mask module being sized and shaped to cover a portion of the face; wherein the mask module further comprises an adjustable upper portion, a middle portion, and a lower portion, wherein the upper portion conforms to at least a portion of the nose, and the middle portion includes a multi-layer mouthpiece connected to the mask module, a first plurality of pleats, and a second plurality of pleats, wherein the first and second plurality of pleats are generally disposed on opposite sides of a first side of the mask module from each other, wherein the pleats provide an accordion-effect in the material of the mask module that defines a space between the interior surface of the mask module and at least the mouth when the mask is worn over the face; and a head module engaging the mask module, wherein the head module is configured to engage at least a portion of the head. ### Claim 2 (depends on 1) The mask of claim 1, wherein the upper portion includes a flexible band disposed therein, wherein the band is conformable to at least a portion of the nose. ### Claim 3 (depends on 2) The mask of claim 2, wherein the band extends within the upper portion across the face, and generally conforms to contours of the face over which the band is disposed, thereby generally dispersing weight of the mask on the face generally along the band. ### Claim 4 (depends on 3) The mask of claim 3, wherein ends of the band extend in generally opposite directions, away from the nose. ### Claim 5 (depends on 2) The mask of claim 2, wherein the band can be re-configured to regulate temperature within the mask module and air volume moving in or out of the mask. ### Claim 6 (depends on 1) The mask of claim 1, wherein shape of the upper portion is adjustable to increase/decrease contact between the mask and the face, thereby adjusting pressure of the mask on the face. ### Claim 7 (depends on 1) The mask of claim 1, wherein shape of the upper portion is adjustable to regulate air volume in and/or out of the mask. ### Claim 8 (depends on 1) The mask of claim 1, wherein shape of the upper portion against the face defines at least one passage for air to move in or out of the mask, wherein the at least one passage regulates at least one of temperature within the space, pressure points of the mask on the face, and air volume in and/or out of the mask. ### Claim 9 (depends on 1) The mask of claim 1, wherein air within the space is generally warmer than air external to the mask module, and the space allows for movement of the mouth and chin while maintaining the mask module substantially in place. ### Claim 10 (depends on 1) The mask of claim 1, wherein the multi-layer mouthpiece comprises an outer material layer, a middle spacer layer, and an inner material layer; wherein the mouthpiece prevents direct ingress of incoming air, with the outer material layer deflecting and diffusing incoming air, and the middle spacer layer providing an air trap warming incoming air. ### Claim 11 (depends on 1) The mask of claim 1, wherein the mask and head modules are sewn together using flatseam construction to minimize seams, wherein at least a portion of each module is made of the same material. ### Claim 12 (depends on 1) The mask of claim 1, wherein the mask module is integrally connected with the head module, and is made of the same material as at least a portion of the head module. ### Claim 13 (depends on 1) The mask of claim 1, wherein engagement of the mask and head modules comprises at least one of a module mask, a full mask, a full mask with neck warmer, a balaclava mask, and a bandana mask. ### Claim 14 (depends on 1) The mask of claim 1, wherein the material comprises an insulating/breathable fabric. ### Claim 15 (depends on 1) The mask of claim 1, wherein the material includes wicking and anti-microbial properties. ### Claim 16 (depends on 1) The mask of claim 1, wherein the material comprises a three layer fabric that includes a waterproof/breathable middle membrane, and wherein the exterior surface is treated with a water repellent finish. ### Claim 17 (depends on 1) The mask of claim 1, wherein the mask is sized and shaped to snugly cover a portion of the head. ### Claim 18 (depends on 1) The mask of claim 1, wherein the upper portion of the mask module conforms to contours of the face, forming a seal between an interior of the mask module and external environment, and thereby preventing goggles worn over the face from fogging.
