Great Mask!
This is a great mask. It comes with a nice neoprene strap, so you don't have to buy one. It has a nice soft skirt that fits well on my face. The windows are very big and let a lot of light in. The clear skirt also lets light in, making for a very illuminated and natural view under water.
