Small field of vision. Won't work if you wear glasses.
This a a good mask for the price. Way better than any rental mask. Make sure you get one with thermal lens. They are totally worth the few extra bucks. I played all day in the rain and my mask did not fog up at all. Other guys that didn't have thermal lens were screwed. They could not see a thing! Great starter mask. Even if you only play a few times a year it is worth the money not to have to put your face in some stinky rental mask. The only think I didn't like was the small lens. If you wear glasses forget trying them with this mask. Comfort was ok once i messed with it to get it adjusted OK.
Good overall mask if you don't want to spend much money. BUY THERMAL LENS!!!
