On new suits all you should have to do is throw it in the dryer on the hottest setting for 1/2 - 1 hour. The only time you should ever have to put it in the wash is if it gets real dirty or bloody. I wash mine maybe once a year ,but I throw it in the dryer after every 2-3 hunts, depending on conditions. Never had a problem with them. Don't forget your head gear and gloves. Good Luck and Good Hunting.
