Are AR glasses for swimming legit? This pair I tested helped me 'hack' my workouts

Form's Smart Swim 2 Pro AR goggles feature Gorilla Glass 3 and an anti-fog coating, but it's the built-in coaching tools that really helped me improve my speed in the water.

• The Form Smart Swim 2 Pro is available for $329, with the premium subscription for $119/year or $15/month.
• The included solution keeps the goggles fog free, and the annual subscription provides extensive training and analysis features.
• Peripheral visibility is limited, the glasses are rather expensive, and the anti-fog spray needs to be applied before each swim.
