All fabric is prewashed in fragrance free detergent before sewing and tumble dried to prevent shrinkage.
For best results and to prolong the life of your garment, I highly recommend hand washing. Alternatively, machine wash on the delicate cycle setting and hang to dry. I do not recommend prolonged dryer use due to risk of damage or loss of hardware, but tossing dry overalls into the dryer for a five minute spin can help eliminate fabric rigidity that accompanies line drying.
