heavy period

Pad lengths commonly range from Regular to Long to Extra-Long. Several overnight/heavy items also advertise extended back coverage or extra rear protection for added security while lying down.

Common comfort and skin-sensitivity features include hypoallergenic or dermatologically tested materials, fragrance-free/unscented labeling, and chlorine- or chemical-free construction.

Typical stay-in-place features are wings, adhesive systems or lock-and-stay adhesives, and secure-fit technologies designed to keep the pad positioned during activity.

Listings commonly use labels such as "Extra Heavy Overnight," "Overnight," and "Heavy" to indicate higher absorbency for heavy or overnight use.

Advertised protection varies by product: some state up to 10 hours of protection, while others state up to 12 hours.
