It gives a great amount of comfort and field of vision.
Finding a replacement lens can be a challenge.
I have had no problem with is mask on the field. It gives a supurb range of vision and the mask has a higher chance of causing bounces because of the "rubber" like matterial on the bottom part of it. I have also noticed that the mask provides a good amount of ventilation.
Overall, this is a great mask in both comfort, style, visibility.
