Essential to the hosiery world, the denier (pronounced DUN-YAY) determines the overall look of your pantyhose. The denier number informs its sheerness, thickness and durability. 

A denier is the technical name for the weight of the pantyhose yarn. The lower the denier, the lighter, thinner, sheerer and more delicate the pantyhose—and the more likely you’ll experience runs. Pantyhose with a higher denier are thicker, heavier, warmer and more opaque and durable.

 The denier number will always have a D after it, making it easy to identify. It’s typically printed on the packaging. Selecting a denier simply comes down to personal preference.
