The new�DS-ADAPT Irons feature COBRA's largest face insert to date and an artificial intelligence-designed variable thickness pattern. By thinning and wrapping it farther around the toe and sole area of the head, the re-engineered face is now 23% more flexible than the previous generation DARSPEED. As a result, the irons produce a robust trampoline effect at impact, generating explosive ball speeds. These technological advancements, combined with the new internal weighting system, which lowers CG to improve energy transfer and launch it higher, make DS-ADAPT the longest irons in COBRA history. The stock steel and graphite shaft offerings are KBS' TOUR LITE and PGI, respectively, while the stock grip is Lamkin's Crossline. COBRA DS-ADAPT Irons Feature: Game improvement iron designed for superior distance and excellent forgiveness SPEEDSHELL face insert is COBRA's largest ever and combines with H.O.T. Face technology to deliver 23% more face flex, unlocking faster ball speeds H.O.T. Face technology variable thickness pattern increases forgiveness by expanding the sweet spot and preserving ball speed on mishits Re-engineered PWR-BRIDGE weight system positions CG lower for improved energy transfer and a higher launch, resulting in greater distance and a steeper landing angle that holds the green better Hollow-body construction (inspired by metal woods) improves weight distribution and creates a more unsupported face to ensure maximum distance Soft foam in the hollow cavity dampens vibrations for exceptional sound and feel Stock Steel Shaft: KBS TOUR LITE Stock Graphite Shaft: KBS PGI Stock Grip: Lamkin Crossline Black (50g, 60R) Authorized COBRA Golf Retailer Product Specs Club Loft Lie Angle Offset Length Stock Steel Swing Weight Stock Graphite Swing Weight Availability 4 19� 62� 5.4mm 39.25" D1 D1 (Stiff), D0.5 (Regular), C9.5 (Senior) RH/LH 5 21� 62.5� 4.6mm 38.5" D1 D1 (Stiff), D0.5 (Regular), C9.5 (Senior) RH/LH 6 24� 63� 3.9mm 37.75" D1 D1 (Stiff), D0.5 (Re
