I have been playing goalie for about a year but I can not find an arm pad I am happy with.
Some are to big and some just weird. I really need to know which arm pad to buy.

Hi, mr. goalie, my son played hockey and lacrosse for years in Ontario. He always bought second hand because h more comfortable with the pads, and any sports equipment, that was already broken in. It is a matter of personal preference really. Do you have any second hand sports equipment stores near you ? I would suggest trying that.
