The proximal layer is forming a first fold with the central venting layer and the central venting layer is forming a second fold with the distal layer to act as a flow restricting apparatus configured to prevent air and flames to get through the FBVT from the outside of the protection footwear and allow air to get through the FBVT from the inside of the protection footwear. A protection footwear including one or many FBVT is encompassed by the present application. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 A fabric vent, comprising: (a) a proximal fabric layer; (b) a central venting layer connected to the proximal fabric layer by an internal fold such that the central venting layer extends over the proximal fabric layer; and (c) a distal fabric layer connected to the central venting layer by an external fold such that the distal fabric layer extends over the central venting layer; (d) wherein the central venting layer comprises (i) a mesh portion that is made from a first material, that is configured to allow a flow of air to pass therethrough, and that is located between the external fold and the internal fold, and (ii) an internal extension fabric portion that is made from a second material that is different from the first material, and that extends from the mesh portion to the internal fold. ### Claim 22 (depends on 21) The fabric vent of claim 21, further comprising means for securing together the mesh portion and the internal extension fabric portion. ### Claim 23 (depends on 21) The fabric vent of claim 21, wherein the central venting layer further comprises an external extension fabric portion, the external extension fabric portion extending from the mesh portion to the external fold. ### Claim 24 (depends on 23) The fabric vent of claim 23, further comprising means for securing together the mesh portion and the internal extension fabric portion; and further comprising means for securing together the mesh portion and the external extension fabric portion. ### Claim 25 (depends on 21) The fabric vent of claim 21, wherein the mesh portion of the central venting layer comprises a fabric material having a series of holes formed therein that are adapted to let air pass therethrough for venting of the garment. ### Claim 26 (depends on 25) The fabric vent of claim 25, wherein the second material of the internal extension fabric portion is a non-mesh material. ### Claim 27 (depends on 21) The fabric vent of claim 21, wherein the vent is configured to block fire from getting through the vent when the proximal fabric layer, the distal fabric layer, and the central venting layer are compressed together. ### Claim 28 (depends on 27) The fabric vent of claim 27, wherein the layers of the vent form a “S” or “Z” shaped cross-sectional configuration. ### Claim 29 (depends on 21) The fabric vent of claim 21, wherein the mesh portion extends a length of between 25 mm and 75 mm in a direction from the external fold toward the internal fold toward, and wherein the internal extension fabric portion extends a length of between 10 mm and 40 mm from the mesh portion to the internal fold. ### Claim 30 (depends on 21) The fabric vent of claim 21, wherein the internal fold and the external fold each has a defined fold shape. ### Claim 31 (depends on 30) The fabric vent of claim 30, wherein the defined fold shape comprises a pressed fabric fold. ### Claim 32 (depends on 30) The fabric vent of claim 30, wherein the defined fold shape comprises a glued fabric fold. ### Claim 33 (depends on 30) The fabric vent of claim 30, wherein the defined fold shape comprises a stitched fabric fold. ### Claim 34 (depends on 21) The fabric vent of claim 21, wherein the fabric of the proximal fabric layer and the fabric of the distal fabric layer comprise the same fabric. ### Claim 35 (depends on 34) The fabric vent of claim 34, wherein the fabric of the internal extension fabric layer comprises the same fabric as the fabric of the proximal fabric layer and the fabric of the distal fabric layer. ### Claim 36 (depends on 35) The fabric vent of claim 35, wherein the internal fold comprises a fabric fold having a defined shape. ### Claim 37 (depends on 36) The fabric vent of claim 36, wherein the fabric of the internal fold comprises the same fabric as the fabric of both the internal extension fabric layer and the fabric of the proximal fabric layer. ### Claim 38 A fabric vent, comprising: (a) a proximal fabric layer; (b) a central venting layer connected to the proximal fabric layer by an internal fold such that the central venting layer extends over the proximal fabric layer; and (c) a distal fabric layer connected to the central venting layer by an external fold such that the distal fabric layer extends over the central venting layer; (d) wherein the central venting layer comprises a mesh portion that is configured to allow a flow of air to pass therethrough, and that is located between the external fold and the internal fold; and (e) further comprising means for preventing a flame from passing through the vent into an interior of the garment when an external fire pressure is applied to the vent. ### Claim 39 (depends on 38) The fabric vent of claim 38, wherein the means comprises a non-mesh material that extends from the mesh portion to the internal fold. ### Claim 40 Footwear having a vent, the vent comprising: (a) a proximal fabric layer; (b) a central venting layer connected to the proximal fabric layer by an internal fold such that the central venting layer extends over the proximal fabric layer; and (c) a distal fabric layer connected to the central venting layer by an external fold such that the distal fabric layer extends over the central venting layer; (d) wherein the central venting layer comprises (i) a mesh portion that is made from a first material, that is configured to allow a flow of air to pass therethrough, and that is located between the external fold and the internal fold, and (ii) an internal extension fabric portion that is made from a second material that is different from the first material, and that extends from the mesh portion to the internal fold.
