When a golf bag is described as having a "pass through" strap system, it means that the straps are designed to go through the bag's handles, rather than around them. This design offers a number of advantages, chief among them being that it helps to distribute the weight of the bag more evenly across your shoulders. Additionally, it can make it easier to get the bag in and out of your car, as you don't have to fumble with straps that are wrapped around the handles.
