Many items use moisture-wicking construction plus absorbent panels or multi-layer leak liners. Period underwear, specifically, lists an absorbent stain-block liner, an odor-guard, and moisture-management layers to protect against leaks and reduce odor.
Size labeling varies by style. Many items are offered S through XL, while some listings include larger options such as 3XL. Individual product pages show sizes like M, L, XL and 3XL among the available choices.
Pack counts vary across the assortment: single-piece items, 2-pair packs, and 3-pair packs are offered.
Period underwear is washable and reusable. The listing advises rinsing in cold water until clear, then machine washing cold with like colors (turn garment inside out). Do not soak or bleach; tumble dry low. Do not iron.
The selection uses several fabrics: nylon/spandex blends for hosiery; cotton blends with polyester and spandex for briefs and period underwear; viscose with spandex in some bikini styles; and mostly cotton with a small amount of spandex in boxer-briefs and some briefs.
Most items are described as opaque. Several product details list sheerness as "Opaque," and reviewers specifically note that the tights are completely opaque.
