Abstract
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.
