D stands for distance, and the Wilson D100 set of golf clubs offers a large, thin, and unsupported clubface for faster ball speeds and unprecedented distance. These irons are designed for players who are working on improving their game. You won’t get stuck on the back nine with these clubs.The Matrix Studio Graphite and True Temper SL-85 Uniflex steel shafts deploy Right Light technology. The lightweight shafts weigh only 65 grams, or just over 2 ounces, and are aimed at creating maximum speed behind a golfer's swing. This design technology combines the stability of stiffer shafts with the soft, easy feel of regular shafts. The set features the Wilson Staff Tour Traction grip and they are longer than the average golf club. Backswings are easier with this shaft, and follow-throughs are cleaner.Once your D100 contacts the ball, the exoskeleton technology takes over. This design feature reduces the moment of inertia, which is essentially how difficult it is to set a static object in motion. The face of the club has a 7% deeper pitch than the previous model. That design element helps you get under the golf balls and gets them soaring. The face is wide, thin, and made of 17-4 stainless steel, all of which combine to help increase speed and distance. The undercut cavity on the head of the D100 irons pulls the weight toward the heel and toe of the iron. That creates a bit of forgiveness for a golfer whose stroke isn’t precision quality just yet. When your strokes land solidly, you’ll get a crisp, satisfying clink sound as the balls go soaring. The sole of these Wilson irons is quite wide. This brings the center of gravity down, making it difficult to pound these irons into the turf by accident. The thinnest hits on your golf balls will land true and send them off and into the air.For improved launch angles, flight speeds, and spin rates, the Wilson Staff uses optimized head proportions throughout this hybrid iron golf set. You do not have to be the best on the green, but having the best equipment can help. From the 5 iron up to the sand wedge, these golfing accessories have a progressive offset. This means the head of the clubface is set back from the hosel or neck, which then leads to the shaft. This improves the odds of hitting the balls straight and getting them higher in the air. Some amateur players tend to hook or slice balls, that is, hit them to the left of the center. This Wilson Golf iron set will help bring down a player’s dispersion angle, sending golf balls down the fairway more directly.Wilson didn’t hold back on the visuals for this golf essential. The polished chrome, single-cast steel head and sleekly designed cavity serve cosmetic purposes as well as offering golf performance enhancing benefits. The red D100 insert gives off a nice high-end feel for the player who's out to improve their golf game. It’s flashy without being so bright that it distracts the user during the follow-through.
