Cobra Core vs Cobra Ultra. What's the difference? 🤔 The main difference between the Cobra Core and Cobra Ultra is that the Cobra Ultra features side temples for increased stability and a more hydrodynamic profile, while the Cobra Core prioritizes comfort (plus space for eyelashes) with no side temples. Both models however utilize our legendary Swipe anti-fog technology and are great for both training and racing. What team are you on, #CobraUltra or #CobraEdge? #PlanetWater #swimming
