I only wash mine maybe twice a season, I put it in the dryer at least once a week as I hunt almost every day of the season. The main thing is to keep it in a sealed container when not using it! Also I would never buy a garment off the rack from a store as the garment has been hanging in that enviorment soaking up that scent. I always order from Scent Lok direct as I know the garment comes sealed in a bag.
