Triathletes and lap swimmers get Corning Gorilla Glass on both sides of the lens in the FORM Smart Swim 2 PRO swim goggles, so the surface resists scratches and damage. A customizable display in the lens shows time, distance, pace, and heart rate in the line of sight. Motion sensors detect stroke and rest on their own, which tracks every length without a button press. The display sits over either eye, and prescriptions up to -3 stay readable. What Our Gearhead® Experts Are Saying:“Fog control comes from the included spray, so I apply it before every pool session. That one step keeps the lens clear through the full set.”
