| Light Bladder-Leakage Liner | Approximately 50–300 mL, depending on size and construction | Occasional drops or small leaks caused by coughing, sneezing, exercise, or light activity | Thin, narrow profile with an adhesive strip; designed to fit regular underwear | Low to moderate | Usually the lightest and least noticeable option; soft topsheets can improve skin comfort | May become saturated quickly during repeated or continuous leakage; limited side coverage |
| Shaped Moderate-Absorbency Pad | Approximately 300–700 mL | Moderate urinary leakage during daily activities | Contoured shape, wider rear area, adhesive backing, and elasticized edges on some designs | Moderate to high | Good balance of discretion, flexibility, and absorbency for daytime use | Requires correct placement; may not provide enough protection for heavy or sudden releases |
| High-Absorbency Anatomical Pad | Approximately 700–1,200 mL | Heavy urinary leakage when a separate pad is preferred over a full protective garment | Longer body, larger absorbent core, contoured fit, and leak guards around the edges | High | Provides more coverage while remaining simpler to put on than a full brief | Bulkier than light and moderate pads; may shift if underwear is loose or poorly fitted |
| Overnight or Maximum-Protection Pad | Approximately 1,000–2,000 mL; actual performance varies by product and test method | Extended wear, nighttime use, or heavier urinary episodes | Extra-long absorbent core, wide rear panel, raised leakage barriers, and moisture-distribution layers | High to very high | Designed to reduce changes during sleep; softer materials can improve overnight comfort | Greater thickness and heat retention; should be changed promptly after saturation |
| Male Guard Pad | Approximately 100–600 mL | Male urinary dribbling and light-to-moderate leakage | Curved, cup-shaped profile with a wider front and adhesive strip for close positioning | Moderate | Compact design can provide good discretion when correctly positioned | Not intended for vaginal anatomy; limited rear coverage and unsuitable for very heavy leakage |
| Booster Pad | Commonly adds approximately 200–700 mL, depending on design | Increasing the capacity of a compatible absorbent brief or protective underwear | Placed inside another absorbent product; some designs have a moisture-permeable backing to let urine pass through | Variable | Can extend wear time when used with a compatible base product | Cannot replace a complete product; an impermeable backing may cause premature overflow if used incorrectly |
| Reusable Washable Pad | Approximately 150–600 mL per pad, depending on layers and size | Light to moderate leakage and users seeking a washable option | Fabric layers, absorbent inner core, waterproof or water-resistant backing, and snap fasteners or a non-slip design | Low to high | Soft textile surfaces can feel comfortable; reusable construction reduces disposable waste | Needs washing and complete drying; fit and absorbency can change with laundering and fabric wear |
| Postpartum and Dual-Use Pad | Approximately 500–1,200 mL, depending on size and absorbent core | Postpartum bleeding, light urinary leakage, or users needing a longer wider pad | Longer shape, broad rear coverage, high-waisted underwear compatibility, and soft surface materials | Moderate to high | Wide coverage can improve stability and reduce edge leaks during movement | Designed primarily for blood and fluid management; may not have the same odor-control or urine-distribution features as continence pads |
