The 3.5 LS weighs 3.5 pounds and is designed for the golfer who loves Sun Mountains hugely popular 2Five but wants a few more features. Like the 2Five, the 3.5 LS is constructed with lightweight nylon fabric, high-strength-to-weight plastic and carbon fiber legs. Adding a pound allowed Sun Mountain to use a thicker strap, a more cushioned hip pad and to add several more pockets. The 3.5LS is the 2017 Golf Digest Editors Choice Carry Bag.
