A ultra-lightweight reinforced flexible garden hose for transporting water, comprising: - at least one inner tubular layer defining a longitudinal axis susceptible to come into contact with the fluid, said at least one inner tubular layer being made of at least one first elastomeric or thermoplastic elastomer material; - at least one outer cover tubular layer intended to be grasped by a user made of at least one second elastomeric or thermoplastic elastomer material; and - at least one reinforcement layer interposed between said inner layer and outer layer; wherein said at least one reinforcement layer consists of rigid or slightly elastic textile threads having at least partially a respective first and second predetermined inclination ( α, β) mutually opposite with respect to said axis; characterized in that each of said first and second inclinations ( α, β) being comprised between 45° and 55° with respect to said axis, so as to oppose the extension and expansion of the hose under pressure thus making it substantially inextensible; and further characterized in that said at least one second elastomeric or thermoplastic elastomer material has a Shore A hardness measured in accordance with the ASTM D 2240 (3") method of 50 to 60, said at least one first elastomeric or thermoplastic elastomer material having a maximum Shore A hardness measured in accordance with the ASTM D 2240 (3") method of 50, said at least one second elastomeric or thermoplastic elastomer material having a hardness higher than or equal to the hardness of the at least one first elastomeric or thermoplastic elastomer material, so as to obtain a very light hose capable of resisting against abrasion. - at least one inner tubular layer defining a longitudinal axis susceptible to come into contact with the fluid, said at least one inner tubular layer being made of at least one first elastomeric or thermoplastic elastomer material; - at least one outer cover tubular layer intended to be grasped by a user made of at least one second elastomeric or thermoplastic elastomer material; and - at least one reinforcement layer interposed between said inner layer and outer layer; wherein said at least one reinforcement layer consists of rigid or slightly elastic textile threads having at least partially a respective first and second predetermined inclination ( α, β) mutually opposite with respect to said axis; characterized in that each of said first and second inclinations ( α, β) being comprised between 45° and 55° with respect to said axis, so as to oppose the extension and expansion of the hose under pressure thus making it substantially inextensible; and further characterized in that said at least one second elastomeric or thermoplastic elastomer material has a Shore A hardness measured in accordance with the ASTM D 2240 (3") method of 50 to 60, said at least one first elastomeric or thermoplastic elastomer material having a maximum Shore A hardness measured in accordance with the ASTM D 2240 (3") method of 50, said at least one second elastomeric or thermoplastic elastomer material having a hardness higher than or equal to the hardness of the at least one first elastomeric or thermoplastic elastomer material, so as to obtain a very light hose capable of resisting against abrasion. wherein said at least one reinforcement layer consists of rigid or slightly elastic textile threads having at least partially a respective first and second predetermined inclination ( α, β) mutually opposite with respect to said axis; characterized in that each of said first and second inclinations ( α, β) being comprised between 45° and 55° with respect to said axis, so as to oppose the extension and expansion of the hose under pressure thus making it substantially inextensible; and further characterized in that said at least one second elastomeric or thermoplastic elastomer material has a Shore A hardness measured in accordance with the ASTM D 2240 (3") method of 50 to 60, said at least one first elastomeric or thermoplastic elastomer material having a maximum Shore A hardness measured in accordance with the ASTM D 2240 (3") method of 50, said at least one second elastomeric or thermoplastic elastomer material having a hardness higher than or equal to the hardness of the at least one first elastomeric or thermoplastic elastomer material, so as to obtain a very light hose capable of resisting against abrasion.
