The X-Strap Dual-Strap System is Sun Mountain's most advanced strap system. The X-Strap Dual-Strap design helps to provide balance when you walk, and you can use the system as either single strap or dual strap. This system also allows you to adjust the tightness of the straps. The two-leg standing system of the SLX, which allows you to stand the bag up while you play, is a common feature on Sun Mountain's golf bags. The leg lock strap is for tucking the legs away when you do not need them. The dividers on the 9.5" top, which are for organizing your clubs, are also standard on Sun Mountain's golf bags. Like Sun Mountain's H2NO golf bag, the SLX has a rainhood for when things get wet. There are color options available for the Sun Mountain SLX golf bag.
