Full-length club dividers prevent club handles from getting intertwined at the bottom of your golf bag. Some of them are also fully lined, which means the handles and shafts of your golf clubs will stay scratch-free while inside. Most premium golf bags come with full-length dividers, which adds some weight to the bag. If you pick up an inexpensive or lightweight golf bag, it’s not unusual to have partial-length club dividers to keep the overall bag weight low.
