How to use
After each wear, rinse your cotton brief in cold water to release any fluids and reduce staining. Then, hand wash or machine wash on cold using a gentle detergent. For best care, place it in a mesh laundry bag to protect the fabric and gusset technology. Avoid using fabric softeners, bleach, or ironing, as these can compromise the absorbent layers and elastics. Always hang dry your underwear to preserve its structure, elasticity, and leakproof performance, skipping the dryer extends its lifespan and keeps it reliably absorbent.
