Black Heather and Athletic Grey: Because of their high cotton content, these colours will shrink. We recommend washing in cold water and tumble drying on LOW heat. 

Charcoal Heather, Navy Heather and Cardinal Heather: Because of their 60/40 cotton/poly blend, these colours won't shrink much at all. Go ahead and wash normal. We recommend tumble drying on low heat to maintain that soft cozy texture.
