Ladies! If you have been dreaming of
indestructible pantyhose, try Sheertex (originally called Sheerlu Genius)! They
are made from the same fibers as bulletproof vests, guaranteed run-and
pile-resistant. The only catch is that Sheertex will be resuming orders on
September 1, 2019, after a new production cycle. The company completely sold
out of its stock.
Katherine Homuth (Hague), the Founder and CEO of Sheertex, and inventor of the Sheerly Genius pantyhose is both thankful for the business, and quite astonished that such run, tear and pile resistant pantyhose were not invented any earlier.

Listed by Time Magazine as one of the 50 best inventions in 2018, the
Sheertex pantyhose invention is disclosed in the patent application US20180368483A1 titled Rip resistant, non-pilling fine knit
garments. A patent application which also presents an extensive list of definitions [0027-0047], so that the terms used to describe the invention do not invoke legal ambiguities or confusion with the more widely understood meanings of certain terms. For example, the term "non-additive", defined in paragraph [0044], in reference to coloring or dying processes, implies a process that does not change the total apparent or non-apparent Denier of the fiber. Similarly, the term "sheer" is defined in paragraph [0027], according to industry standards, as a knit with an appearance that is 30 Denier or less. The distinction between "apparent Denier" and Denier is also explicitly defined as "the total denier of visible fibers used in the knit" [0042], excluding the clear fibers, considered non-apparent within the context of the invention.
The Sheertex invention arises in a prior art situation where Denier, the measurement of the
linear mass density of fibers per of 9000 meters of fiber is traditionally inversely
correlated with the sheerness of a knitted garment (e.g.; hosiery). Sheerness
is a measure of how much light can travel through a garment. Thus, the higher the density of the
fiber the less light can pass through. For hosiery, sheerness is also associated
with low tensile strength or resistance to tearing (i.e.; the maximum amount of
stress before a garment loses its elasticity). Thus, low Denier (between 1 and
30) is associated with sheerness (a high amount of light passing through the
hosiery), resulting in a fragile garment considered disposable. Denier between 31 and 100
is semi-opaque hosiery with little light passing through, and above 100 Denier
is no light passing through and completely opaque hosiery, resulting in relatively more resistant hosiery.
In response to the prior art, the Sheertex invention offers a product that is sheer, elastic and high tear-resistant,
using an UHMWPE (Ultra High Molecular Weight Polyethylene) fiber, in combination with a clear Spandex (i.e. elastic) fiber.
The clear Spandex fiber makes it possible to produce 32 Denier hosiery with the
appearance of 30 Denier. The combination of fibers also has increased moisture-wicking and anti-microbial properties, and it is possible to obtain hosiery of different colors using a non-additive process.
Finally, the invention pantyhose also have “abrasion pads” knitted in areas of high friction such as heels and thighs to prevent the appearance of “bald spots”. Pantyhose bald spots are those areas where the knit thins out and loses elasticity, due to wear of the less resistant clear Spandex fiber, relative to the indestructible (bulletproof) UHMWPE fiber.

For pantyhose stuffed and dragged on asphalt behind a car to
mimic a fall, wearing pantyhose, as part of a variety of Gizmodo-organized testing, performed independently of Sheertex, the Sheertex pantyhose were found destructible. However, in comparison to
regular pantyhose which are destroyed on impact, Sheertex pantyhose were definitely
found “a helluva lot” more resistant (Song, 2019).
Thus, ballistic-fiber Sheertex pantyhose finally fulfill the dreams of many women for pantyhose that are both sheer and highly resistant to tearing, wear, rip and run, even if it comes at the higher price of $99.
Included below, the abstract of the Sheertex pantyhose invention,
together with the patent application Figure 1 drawing. The Figure 1 drawing shows an
exemplary embodiment of the invention tights 10, front and back, including abrasion pads on heels 60 and
thighs 62.
The present invention relates to knits that can be used to make rip - resistant sheer hosiery or similar garments, using a specific combination of UHMWPE fiber and stretch fiber, such as spandex. The knit has rip - resistant and anti - microbial properties. Details are provided to avoid problems with pilling and the appearance of bald spots during use. A variation of the knit is useful for activewear. [Abstract US20180368483A1]
