There are three very different models in the new 2026 Callaway Quantum range, but it’s the Quantum Triple Diamond that caught my eye instantly. Designed for the better, more confident player, this model prioritizes low spin, compact shaping, and workability over forgiveness.
This is, without a doubt, one of the best-looking fairway woods Callaway has ever produced. I love the mix of the gloss carbon crown and tones of grey on what is a smaller and more compact head than the Quantum Max model. As someone who naturally draws the ball, I also like the fact that the head wants to sit ever so slightly open, so I can send the ball off to the right before it turns over.
One of the standout features for me is the clean banner strip across the crown. It’s a subtle matte finish against the gloss carbon that frames the ball beautifully, and I found it helped me square the face to your target instantly without looking like a loud alignment aid, helped by the full-length grooves. I think It certainly rivals the looks of any fairway wood on the market in 2026.
I was eager to see if the Triple Diamond could deliver on its promise of tour-authentic performance and become one of the best fairway woods of 2026, so I put it through its paces on the Foresight Sports GC3 launch monitor and took it out on the course to see how it handled various shots.
The first thing that jumped out was the ball speed. At just under 159 mph, it was around 2.5 mph faster than the Max D (a more forgiving fairway wood option), which translated directly into more distance. The launch was still fairly high at 11.9°, and with the lower spin sitting on average at 2978 rpm, I saw an impressive average carry of 259 yards, all through a high but penetrating flight.
This bullet-like flight soared through the air and was barely touched by the slight crosswind I conducted my testing in. It didn't have the floaty nature of the Max D - instead, it reached its peak height and just kept on moving forward.
For a player with speed, this club is a cheatcode due to how workable it still is from the fairway. I found I could easily manufacture shots into the greens, hitting flat draws but also, spinny, high fades when I needed to land one softly. Given how small the head is, it was actually fairly forgiving, not quite as much as some of the most forgiving models on the market, but better than I expected.
As with the rest of the Callaway Quantum family, the Triple Diamond features the new Speed Wave 2.0 tungsten weighting and Ai10X Face, but the application here is different. There is an extra interchangeable weight that pushes the CG further forward to kill spin and increase ball speed.
Callaway has also deepened the face slightly, a common trait in their tour-inspired heads, which I felt increased the performance from the tee and forced me to hit down and compress the ball from the fairway.
The Callaway Quantum Triple Diamond fairway wood certainly isn’t for everyone, but for those who possess the skill to unlock its potential, I believe it could truly be a game-changer. It demands a decent strike and a fairly fast clubhead speed to activate that low-spin performance, but if you can input that, the reward is a fairway wood that feels incredible, looks stunning behind the ball, and offers a level of control and power that is going to be hard to beat in 2026.
