The Envy has a smooth modern feel that fits in the hand perfectly, lending confidence for both putt and approach duties. The Envy exhibits reliable high-speed stability and a minimal fade. With a slightly lower profile and cruising speed than the Ion and Anode class, the Envy is a uniquely “lid-like” stable putter. Our original premium plastic blend, Proton is a translucent core material with stunning optical clarity and vibrant colors. Proton has similar durability and slightly more grip than our Neutron plastic. The colorful candy plastic core yields a different aura to each model and especially suits LED-lighted night play. Axiom Proton features vibrant color GYRO rims.
