The robust external layer protects the air hose from wear and degradation due to abrasion. The external layer may be made of a fabric with an abrasion resistance of at least 22,000 cycles to failure as measured using the ASTM D 3884 standard. This external layer fabric may be composed of filaments having a linear density of about 1,000 denier. The external layer fabric may weigh about 10.8 ounces per square yard. ## Claims ### Claim 1 An air delivery hose assembly, comprising an external layer comprising a fabric having an abrasion resistance of at least 22,000 cycles to failure as measured using the ASTM D 3884 standard. ### Claim 2 (depends on 1) The air delivery hose assembly of claim 1, further comprising an inner layer. ### Claim 3 (depends on 2) The air delivery hose assembly of claim 2, further comprising an insulating layer disposed between an inner surface of the external layer and an outer surface of the inner layer. ### Claim 4 (depends on 1) The air delivery hose assembly of claim 1, further comprising a structural reinforcing element. ### Claim 5 (depends on 4) The air delivery hose assembly of claim 4, wherein the structural reinforcing element comprises a coil of wire. ### Claim 6 (depends on 1) The air delivery hose assembly of claim 1, wherein the fabric comprises nylon. ### Claim 7 (depends on 1) The air delivery hose assembly or claim 1, wherein the nylon comprises nylon 6,6. ### Claim 8 (depends on 1) The air delivery hose assembly of claim 1, wherein each filament of the fabric has a linear density in the range from about 800 to about 1,200 denier. ### Claim 9 (depends on 1) The air delivery hose assembly of claim 1, wherein each filament of the fabric has a linear density of about 1,000 denier. ### Claim 10 (depends on 1) The air delivery hose assembly of claim 1, wherein the fabric has a weight in the range from about 2 to about 17 ounces per square yard. ### Claim 11 (depends on 1) The air delivery hose assembly of claim 1, wherein the fabric has a weight of about 10.8 ounces per square yard. ### Claim 12 (depends on 1) The air delivery hose assembly of claim 1, wherein the fabric has a color of at least one of CMYK standard format color 0,40,100,0 or RGB standard format color 255,153,0. ### Claim 13 (depends on 1) The air delivery hose assembly of claim 1, wherein the fabric comprises a waterproof coating. ### Claim 14 (depends on 13) The air delivery hose assembly of claim 13, wherein the waterproof coating comprises polyurethane. ### Claim 15 (depends on 3) The air delivery hose assembly of claim 3, wherein the insulating layer comprises a radiant barrier. ### Claim 16 (depends on 3) The air delivery hose assembly of claim 3, wherein the insulating layer has a reflectivity of about 0.97 that is obtained by a measurement method based on ASTM C 1371. ### Claim 17 (depends on 4) The air delivery hose assembly of claim 4, wherein the structural reinforcing element is external to the external fabric layer. ### Claim 18 (depends on 17) The air delivery hose assembly of claim 17, wherein the structural reinforcing element is covered by an abrasion-resistant scuff strip. ### Claim 19 (depends on 18) The air delivery hose assembly of claim 18, wherein the abrasion-resistant scuff strip comprises at least one of rubber or the fabric having an abrasion resistance of at least 22,000 cycles to failure as measured using the ASTM D 3884 standard. ### Claim 20 (depends on 4) The air delivery hose assembly of claim 4, wherein the structural reinforcing element is internal to the external fabric layer. ### Claim 21 A method of manufacturing an air hose assembly, comprising: creating at least one panel comprising an external layer made of a fabric having an abrasion resistance of at least 22,000 cycles to failure as measured using the ASTM D 3884 standard;
