Reviews Summary
Generated by AI from 100 most recent customer reviews
Last updated 2 months ago
Customers say these high-rise underwear are extremely comfortable and feel like wearing nothing at all. They appreciate the soft, silky fabric and the confidence they provide for bladder leaks and light incontinence. Many find them perfect for workouts, with no panty lines and excellent all-day protection. Users consistently mention the comfortable fit and reliable leak protection. However, some note sizing inconsistencies between colors and styles, with several finding them smaller than expected. A few customers mention the waistband sits very high, which some love for today's fashion while others find it too high. Common feedback includes concerns about the protective pad placement and occasional fit issues around the legs.
