The Sync is designed for use on push carts. We started with a top and bottom designed to nest in the upper and lower bag rests of Sun Mountain push carts. Then we moulded the bottom so it fits over the lower bag rest of the Speed Cart V1, SV1 and Micro-Cart, minimizing side-to-side bag movement; All pockets are forward facing and accessible when the bag is on a cart. There are 15 individual full-length dividers including a separate compartment for your putter. The Sync also works well on the Speed Cart V2 and riding carts. Includes a matching rainhood.
