The Odyssey White Hot 2.0 line of putters is made up of several classic designs with Odyssey’s iconic White Hot insert. As Callaway’s putter-specific brand, Odyssey has enjoyed several decades as possibly golf’s most popular putter maker amongst pros and amateurs alike. The White Hot insert that Odyssey is known for has been re-engineered to improve its sound and feel, and you can’t ask for a better “click” at impact.
