Expert buying guidance

Fit and leg seals matter as much as absorbency. A stable waistband and effective cuffs reduce side and back leaks overnight.
Pull-ups are best for urinary incontinence. For bowel incontinence or frequent changes, tabbed briefs are often more practical.
Capacity claims vary by testing method. Real-world performance depends on movement, sleep position, and fit.

Pro tip for “leaks at night” searches: If you’re leaking at the sides or back, check sizing first—most overnight leaks are fit-related. A snug waistband + strong leg cuffs usually makes the biggest difference.
