In a show of support, Callaway Golf has teed off a partnership with Cancer Council for The Longest Day golf challenge, launching a limited-edition daffodil-branded Callaway Chrome Tour Truvis golf ball.

“We all have a reason to help this cause. My personal one is my dad, Neil, who passed away from pancreatic cancer 14 years ago,” said Matt Meredith, Managing Director of Callaway Golf South Pacific.
“We have all been touched by cancer. Some are facing it right now. I’m so glad that we can support Cancer Council to prevent cancer, empower people and save lives!”
