The Quantum Triple Diamond is the compact, low-spin model in Callaway's 2026 Quantum driver line, built for better players who want workability and a penetrating flight. It debuts the Tri-Force Face, which layers ultra-thin titanium, Poly Mesh and carbon fibre into one AI-tuned face, sitting on Callaway's lightest 360-degree carbon chassis with a 10-gram neutral/fade weighting system. The 450cc head runs deeper-faced and fade-biased, the shape many tour players prefer.
