Maruman Shuttle M-Sole Womens Fairway Wood Maruman's unique patented "M-Sole" design repositions the weight with a deeper center of gravity to strengthen the sole and improve the balance for a more stable club head and better control. Shuttle M-Sole fairway woods feature an extremely light weight, thin 0.4mm titanium top crown which permits weight to be redistributed producing a lower center of gravity for improved trajectory and greater ease hitting from tight lies. The Shuttle club face is made with a very hard 771 maraging steel enabling for a very thin 1.9mm face thickness for higher repulsion. The thin, hard face design creates greater ball speed and increased distance. Luxurious scratch resistant deep black IP chrome based finish minimizes glare and improves durability of the face and sole.
