This is an very common question when it comes to goalie gear. 

What does full right and regular mean?

This is the meaning of which hand you have the stick or blocker, to put it simple. If you hold the stick in the right hand you need to choose "Regular". When you hold the stick in the left hand you need to choose "Full Right"

• Regular: This means that you have the blocker on the right hand together with the stick. Also then you have the catcher in the left hand. Then you need "Regular" for blocker, catcher and stick. 
• Full right: This means that you have the blocker on the left hand together with the stick. Also then you have the catcher in the right hand. Then you need "Full Right" for blocker, catcher and stick.
