Vintage non-run mesh all-nylon non-stretch stockings with full Reinforced Heel and Toe (RHT) by Impact. These nylons are knit in 'Enkalon' nylon. These stockings have been manufactured using a process that assists the fabric to resist ladders far more than normal. The denier isn't stated but we are of the opinion that these classic non-run mesh stockings are knit in a 20 denier yarn. A seam extends full-length under the foot from the reinforced toe to the reinforced heel. The welt is in lovely slinky plain knit, and there is no under/afterwelt.
