Vintage non-stretch seamfree micromesh 15 denier 100% nylon (under the brand name of 'Helion') stockings, with Reinforced Heel and Toe (RHT). The stocking top (welt) is shorter than is customary (37mm) but the underwelt is significantly deeper than normal (80mm). The micromesh knit changes to slinky plain knit under the foot for additional sensuous comfort. The denier is not specified on the original cellophane packs, but we are confident that these are knit in ultra sheer 15 denier yarn.
