The best underwear for periods is the pair that matches your flow, fits securely and can be washed according to its care instructions. Check absorbency claims carefully and treat period underwear as one part of your personal protection plan.
Compare absorbency honestly
Brands may describe capacity using teaspoons, millilitres or comparisons with pads and tampons. These measures are not always directly comparable, so read the product page and choose a higher absorbency for heavier days if needed.
Check the construction
Look for a gusset that extends far enough for your body and a waistband that stays flat without digging in. A close fit helps prevent leaks, but the leg openings should not pinch or leave marks.
Fabric and care
Moisture-managing fibres can feel more comfortable, while cotton gussets may suit sensitive skin. Rinse according to the label, avoid fabric softener and allow the garment to dry completely before storing.
Frequently asked questions
Can period underwear replace other protection?
It can for some people and some flow levels. Follow the manufacturer’s capacity guidance and change or combine protection when necessary.
How long does period underwear last?
It depends on the garment, washing routine and frequency of use. Replace it when absorbency, elastic or fabric condition has noticeably changed.
