More than just a good idea, the Idea Tech a4-R Hybrid Irons Set by Adams Golf® is designed to help better players play better and average players play better. The Idea Tech a4-R Hybrid Irons Set includes high-performance, tour-proven hybrid irons plus gap and pitching wedge—it's the lowest CG iron in its class with high MOI. Crafted from quality 8620 carbon steel for the ultimate in feel, the Idea Tech a4-R clubs feature Adams' patented Boxer Technology which increases MOI for straighter, longer shots. The Quad Cavity-Back design pushes weight to the perimeter for improved forgiveness, while the forged stabilizer bar sets mass behind point of impact for improved feel and feedback. The club face has high-performance milled grooves designed to provide optimal spin from all lie conditions. Four-way tour cambered sole design reduces ground interaction for more consistent results.
