autoFlex Iron SF305 launches — the lightest, softest iron shaft in the line
2026-04-15
The autoFlex Original line now reaches the whole bag. Iron SF305 is the lightest and softest iron shaft Dumina has built: 47 grams, 220 CPM.
Until now, golfers who put autoFlex in the driver, wood and hybrid had to change feel completely at the irons. SF305 closes that gap, so the same easy-swing character carries from the tee to the approach.
SF305 joins the existing SF405 and SF505 iron specs. Full figures are on the autoFlex Original page.
