A flexible cryogenic hose for liquefied natural gas (LNG) transfers is described. A cryogenic LNG transfer hose includes an LNG transfer hose carcass including an inner coil forming an inner diameter of the LNG transfer hose carcass, at least one elongate sheath form-fitted about an outer surface of the inner coil, wherein the at least one elongate sheath is impermeable to natural gas, and an outer coil forming an outer diameter of the LNG transfer hose carcass. A marine LNG transfer system includes a cryogenic flexible hose fluidly coupling a transferring LNG carrier located offshore and an LNG receiving vessel, the cryogenic flexible hose comprising a coil, at least one natural gas impermeable elongate sheath form-fit about an outer surface of the coil, and wherein LNG flows through the cryogenic flexible hose during transfer of LNG between the transferring LNG carrier and the LNG receiving vessel.
