Efficient at sea
"90 minutes of swimming at sea for 2. 6 km. Water temperature 28 °C / 82°F. Perfect comfort, no pressure sensation. Very clear visibility the water slides on the glasses as if they were hydrophobic. After 45 minutes, a slight fog formed that remained stable and not very annoying that I rinsed after 70 minutes because I had to see in the distance precisely where my exit point was. No glare despite the setting sun. The strap may be a little short when you have to wear the Swim cap in winter"
