A lot of people ask me about deniers. What do they mean and which one is the right one for me. Basically the way I understand it, denier is a way to measure the thickness of the threads in the pantyhose. The higher the denier the thicker the pantyhose will be. The thinnest denier stocked on HosieryAndSockOutlet.com for women 12 denier. Obviously these will not last as long as a thicker denier. The thinnest denier stocked for girls is 30 denier. The thickest product stocked is Palm model 100. Though people think they're 100 denier, it's actually a model number. I'm not sure what the actual denier is for that product but I would guess it's more than 80 denier a.k.a. "bullet proof".
