Izzo Only the pioneer and creator of the original Dual Strap golf bag could come up with a single replacement strap that functions like the same. Izzo Golf's innovative Side Winder strap features a ergonomic, pre-molded shape to automatically swing and balance your golf bag behind you without the need to have to reach back and secure a second (dual) strap. The Side Winder combines single strap convenience/ease of use with dual strap weight balancing and carrying comfort.
