This is a good starter mask.  I would recomend this to someone who is just starting out.  Lets start with the goo things about the mask.  I like how it has the hard plastic covering the ear, forehead, and nose, areas.  The field of view on this mask is not to bad.  Now lets move on to the not so god things. This mask will fog alot when you breath heavily if you don't have a thermal lens. It is kind of large and it limits the amount that you can turn your head.  When you move your head or neck it will touch your shoulders or neck.  This mask usualy costs around $20-30 for singel lens, or $30-40 for a thermal lens.
