FLO Period-Proof Black Hipster Brief XL — Holds 4 Tampons Worth of Flow

Meet FLO Period-Proof Black Hipster Brief in size XL. This everyday essential blends comfort with practical protection, so you can focus on your day instead of the mess. The underwear is designed to hold up to the equivalent of four regular tampons of flow, giving you a discreet option you can trust when you’re on the go.

Made from sustainably sourced cotton from the Better Cotton Initiative, the fabric feels soft against the skin and breathes with your movements. The hip-hugging silhouette stays in place through commuting, workouts, or relaxed days at home, while the breathable design helps you stay comfortable all day long.

Reliable protection you can count on
