The Adams Idea Tech V4 hybrid irons are built to maximize ball speed and help players get the ball into the air easier to provide increased distance. The all-hybrid set includes traditional hybrids as well as hybrid irons. The hybrids feature the Velocity Slot technology that now has a channel connecting the clot in the crown and sole. This allows for a greater Characteristic Time, a measure of how long the ball stays on the club face, to have a more spring-like face. The slots are plugged with inserts to conform with USGA rules and give the hybrids a crisper, iron-like feel.
