Oakley Flak 2.0 XL Sunglasses Review

Our Gear

We reviewed a pair of polished black Oakley Flak 2.0 XL sunglasses with Prizm Golf lenses (Product Link) over a weekend, and they definitely earned their spot as a top sports frame.

Keep reading as we explain what makes these sunglasses so great on and off the field (or golf course)!

Initial Impressions

We’re already fans of the Oakley Half Jacket 2.0, so we were excited to get our hands on the Flak 2.0 XL.

And after unboxing this pair, the first thing we noticed is the updated design compared to the Half Jacket 2.0. Overall, the Oakley Flak 2.0 definitely feels more modern and updated.

There’s been plenty of input on the Flak from many wearers on the forum, and it’s become common knowledge that this is a certified win of a pair! But keep reading for our full review of why this pair stands out!

Frame, Fit, and Design

Firstly, as we mentioned above, the Flak 2.0 XL features an updated design from the classic Half Jacket. And while it still has the classic half-rim lenses, the temples feature a more modern and edgy design that makes this frame look fast!

And the temples feature Oakley’s signature Unobtainium earsocks for added grip. You’ll also notice that the Oakley Flak 2.0’s earstems tilt slightly inward. This won’t matter for most people, but it may if you have high cheekbones. That’s because the frame sits a bit more flush with the transition from temple to cheek. If you have higher cheekbones, you’ll want to check out Oakley’s Low Bridge Fit.

In all, theFlak2.0has a pretty versatile fit that runs secure but light. I could see why people find the Oakley Jawbreaker front-heavy if pairs like this and the M-Frames are their baselines.

Overall Aesthetic

Initially, we thought the Flak 2.0’s looked small and simple compared to other pairs. But in my hand, we like the subtle details that add up. For example, the very slight flares in the nose, shaping of the orbitals to follow the eye socket, the sculpted temples and transitions, the ribs in the stems I mentioned before, as well as on the earsocks. And all these features are functional towards rigidity, weight cutting, and handling convenience.

One doesn’t need to be meticulous with design to make a perfectly functional pair, but Oakley went that extra mile.

Nose Pad Replacement

The Flak 2.0 XL features nose pads that hook onto the frame, similar to the Radar series. But unfortunately, the Radar nose pads are not compatible with the Flak 2.0. While you may be able to get the Radar pads to work, it’s sloppy because they’re meant for a larger base.

Onthatnote, I found the smaller mounting points of the Flak 2.0’s nose, and the smaller pads made replacing the pads more of a chore than usual.

Overall I found the nose pads to be such small pieces to grip without a safe place to secure the frame in your hand. Ultimately, smudges seem inevitable when trying to swap the nose pads. Nonetheless, this is an easy pair to clean since it’s a half-frame. I assume Oakley didn’t reuse the “plug-in” setup from the XX and Pit Boss 2 because the rubber layer is pretty thin, therefore feeling a bit hard.

Earsock Replacement

Similar to the nosepads, you can easily change the earsocks on the Oakley Flak 2.0 XL. Overall, we like the ear sock design on the Flak 2.0.

Oakley uses the hole built into the temples/frame as a locking point which is very practical and user-friendly. Once the socks have been popped out of the hole, they slide off easily.

Most people won’t need to change their earsocks too often, but it can be useful for cleaning your earsocks after a sweaty day!

Size and Dimensions

The Oakley Flak 2.0 is a medium-sized frame that fits well on most faces. The XL lenses help to provide additional coverage for sports or if you have a larger face. We’ve included the complete dimensions below:

• Frame Width: 126mm
• Frame Length: 133mm
• Bridge Height: 12mm
• Lens Heigh: 59mm
• Lens Width: 38mm

Prizm Lenses and Coverage

The Oakley Flak 2.0 XL features a half-frame design similar to the original Flak or Half Jacket. And the XL, in its name, refers to the extended lenses that flare out to the sides of the frame, providing additional coverage.

Our review pair featured Prizm Golf lenses that are designed for golfing but still worked great off the field. We won’t go into too much detail on our specific lenses here, but you can check out our guide to Prizm Lenses for more.

The Flak 2.0 frame seems to sit closer to the face than other sports pairs. This helped to make the frame and temples less noticeable in our field of view. And the wind deflection from the lenses and frame is definitely sufficient for cycling.

Overall, we found the Flak 2.0 XL to have fantastic coverage, and the expanded lenses definitely provided additional peripheral vision. There were still some gaps off to the sides, but we’d say the Flak covered 90% of our field of view.

Final Thoughts – Are They Worth It?

Yes, Oakley Flak 2.0 XL sunglasses are worth it for anyone with an active lifestyle or athletes. This frame is lightweight durable, provides maximum comfort and lens coverage for a dual-lens design!

After wearing these for a weekend, it’s obvious why these are a best-selling pair for Oakley. And now, these have quickly become a staple in our lineup of sunglasses.
