I bought a pair when looking for Cressi fins to go snorkeling with.
Cressi soft silicone goggles are simply matchless. I have bought a pair for everyone at home.
Don’t get those hard ones from Arena and Speedo anymore. Just try the Cressi (mine is the Flash with a red brow) and you will thank me for it.
