Please Note

Some materials are made of cotton, which's more sweat-absorbing and breathable than other products, so it's relatively easier to absorb water and sweat. If it's simply washed with water or soap, it's not easy to wash clean. Residual odor is normal, so please noted when you're cleaning that you must use a special laundry detergent or laundry soap for underwear to reduce the occurrence of residual odor.
