Product Description

Total security from morning to night. Upgrade your cycle with the Super Leakproof No-Show High Rise, engineered for those who prioritize extra coverage and comfort. The extended gusset provides 360-degree protection against leaks, making it an ideal choice for heavy days or postpartum recovery. Crafted from moisture-wicking, anti-odor fabric, it keeps you dry and fresh without the bulk of a pad. Ditch the disposables for this high-performance period solution that flatters your curves and stays in place.

Comfort-First Fit

Sits at the natural waistline and provides medium bum coverage.

Worry-Free Protection

Patented leakproof technology delivers a barely-there feel, while bonded edges prevent side leaks.

Heavy Absorbency

Absorbs 6 Super tampons worth of liquid—perfect for heavy flow days, overnight protection, and light bladder leaks.

No More Panty Lines

Made from our signature buttery-soft fabric and designed to be invisible under clothes, including leggings.

Easy to Wash

Machine washable, just like your regular underwear.

Reviews Summary
Customers say these leakproof underwear are exceptionally comfortable and soft, feeling like regular underwear without bulk. They praise the excellent fit and reliable protection for periods and bladder leaks. Many appreciate the high-rise coverage and smooth, no-show design under clothing. Users frequently mention the durability, with pairs lasting years through regular washing. The stretchy, breathable fabric stays in place throughout the day. While most find them true to size, some recommend sizing down for a snugger fit. A few note concerns about recent design changes making them bulkier, and some mention limited color options for heavy protection styles.
