About half the teams in the NHL have alternate jerseys to go along with their regular home and road uniforms. Winter Classic games, Stadium Series games, holidays, anniversaries or just plain old greed may cause the creation of new jerseys, some meant to be worn only once. This season, the Ducks, Avalanche, Sharks and Islanders are among the teams adding new jerseys for one reason or another.
Every time a team introduces a new extra jersey, it is scrutinized immediately across social media while simultaneously being pushed by the team on customers at retail.
