Description
The Callaway Great Big Bertha Epic Sub Zero fairways feature four of Callaway’s technologies to create a longer, more forgiving, and low-spinning fairway. First is a crown made of triaxial carbon, which reduces the weight of the crown by 78% compared to a traditional steel crown and results in the lowest CG of any Callaway fairway to date. The second technology is Hyper Speed Face Cup technology, a thin and flexible rim around the inner side of the face which flexes and releases more uniformly and efficiently at impact for higher ball speeds. Next up is Callaway’s Speed Step technology which enhances the head aerodynamics and results in faster club head speeds. Lastly, the Epic Sub Zero features two interchangeable weights in the sole to adjust the launch and spin rate helping players maximize distance for their particular swing.
