How does a brolly holder help me play better golf? ?
Assuming you don't have a very accommodating caddie to hold your brolly, attaching our brolly holder to the handle of your Power Bug lets you walk along with you and your clubs staying dry. The more comfortable you are, the better you play.
Also apologies for answering a question with a question but .... without a brolly holder where do you put your brolly when you take a shot ???
