I’m so in love with this #Fullface #Snorkel #seaview #madk! It is amazing. It stays clear. No fogging. No leaks. It’s comfortable and it is everything you’d expect from a great mask. I have two full face snorkel masks for me and my son and I’m going to get two more for my mother and my youngest son. You do have to pay attention to make sure you order the correct size. Buy this. You won’t regret it. I had to update my review after finally going swimming because when I first got it, I couldn’t use it yet but now I’ve been three times and this mask has held up all day every time. I’m sure it will be used many many more times.
