## Our take

The Oakley Flak 2.0 XL is the workhorse half-frame golf sunnie, the bigger-lens version of the standard Flak, fitted with Oakley's Prizm Golf tint. It's aimed at golfers who want proper coverage and grip rather than a fashion statement.

**What's great:** The Prizm Golf tint genuinely earns its keep, lifting contrast so a white ball pops against blue sky and the lens picks out cuts between fairway and rough. The O Matter frame is properly light and you forget you're wearing them, and the Unobtainium nose pads and earsocks get grippier as you sweat, so they don't slide down your nose on a hot round. The XL lens gives wraparound coverage that cuts glare at the edges, and the build is Oakley-tough, so they take knocks in the bag.

**Worth knowing:** Not for big heads. The 37mm lens height and narrowish bridge mean larger faces feel pinched and the coverage shrinks, so try before you buy. The contrast claims are oversold too: owners reckon finding a ball in thick rough or reading grain on the greens is actually easier with them off, so don't expect a cheat code. The nose pads can pop off, and the darker Prizm Dark Golf variant is too dim for anything but bright sun. Looks divide people, more tactical SWAT than country club.

**Verdict:** If you've got a medium face and want a grippy, light, no-slip pair that genuinely helps you track the ball against the sky, I rate these. Big-faced lads and anyone expecting magic green-reading should look elsewhere or size up.
