As your Clan earns promotion in clan divisions new rewards will be unlocked, including additional golf bag load-outs.

These extra golf bag load-outs allow you to have multiple golf bags containing different clubs from your collection.

You can edit all unlocked golf bags, by selecting the golf bag icon from the main menu screen.

This allows you to quickly switch between your different golf bag load-outs between each match. 
This is extremely beneficial during tournaments, when different clubs are more suited to different holes and conditions.
