After all that exercise, the last thing you want is to hand-wash your underwear. The good news is that Marie Jo Intense sports lingerie can be machine-washed at 40°C.
Use the practical Marie Jo Intense lingerie pouch to protect your lingerie in the machine. Avoid detergents for wool and silk. Regular detergent will do just fine.
Lay your Marie Jo Intense lingerie on a flat surface to dry, but never in direct sunlight or on a heat source, like a radiator.
