Instructions
Wash your hockey jersey in the washing machine on the hottest temperature setting. Under normal conditions, for a cotton and/or polyester hockey jersey you don't wish to shrink, you would wash it on the coldest temperature setting.
Dry your hockey jersey in the dryer on the hottest temperature setting.
Remove your jersey from the dryer and determine if you wish to have an even tighter fit. Repeat the washing and drying on the hottest settings until you get the desired fit.
