We compared two adult swimming goggles: the Speedo Biofuse 2.0 and the Zoggs Phantom 2.0.

What we looked at

Seal and frame design, strap, anti-fog, lens, and price.

The verdict

If you want a flexible-frame goggle with an anti-fog spray and a huge review history, the Speedo Biofuse 2.0 is the pick at £12.33. If you would rather save £3.34 and want a clear lens and a hypo-allergenic silicone seal, the Zoggs Phantom 2.0 is the alternative, at £8.99.
