Absorbency labels vary by brand. Common levels include Very Light (minimal protection), Light, and Regular, with terminology differing between listings.
Most liners are offered in a regular length, while some brands provide extra-long options or specially shaped liners designed for thong underwear.
Design features that aid discretion include a thin, flexible profile for a 'barely there' feel and an adhesive backing described as 'stay‑put' to keep the liner secure during daily activity.
Many liners are promoted as hypoallergenic and dermatologically or gynecologically tested. They are often formulated without fragrances, dyes, or chlorine to be gentler on sensitive skin.
Cooling or herbal-infused liners are described as infused with herbs that provide a cooling or minty sensation. Many reviewers note a refreshing cooling or tingling feeling.
