Buying Guide

Choose the right fabric

Look for breathable, moisture-wicking materials such as merino wool for odor control or bamboo-rayon blends for softness and natural moisture management

Consider period-proof features

If you need leak protection, prioritize briefs labeled absorbent or leakproof with multilayer construction designed for internal moisture control rather than bulky padding

Check washability and care

Activewear briefs should be machine washable and retain absorbency and shape after laundering; prefer washable-underwear tags and simple care instructions

Assess fit and coverage

Select a cut—bikini, brief, or full coverage—that matches your activity level and support needs; brands often specify cut in product tags

Weigh user ratings and durability

Combine average star ratings with material tags like merino-wool or bamboo-rayon to gauge long-term comfort and abrasion resistance for regular use
