What you need for goalie gear:
Goalie Gloves: special gloves with more padding.
Goalie stick and head
Goalie chest protector
Throat protector-these come in a tie on version and a permanent one that attaches to the helmet.
Goalie pants are optional but are a nice luxury for younger goalies.
A protective cup is mandatory for goalies.
Gear can be purchased from any of the retailers listed on the Where to Buy page.
