BR-D4 is Mizuno’s largest cart bag which means you don’t need to leave anything at home as this one no less than 20 different pockets and compartments. A Mission Control panel makes it easy to access what you need most often – from your rangefinder, score card and course guides to pitchfork, all in one and the same place. The bag also has an extra large cooler compartment which keeps your drinks bottle cool on warm days. The bag has a 14-way top with an integrated putter holder so that every club has its own place. Every club compartment has a full-length divider which gives the clubs extra protection when you transport the bag. The bag’s base plate has tracks which makes it extra stable when attached to a trolley.
