Here's a cheap little secret that you need to try before spending any extra money on a goggle fan.
Place a strip of paper towel across the top of your nose before you put your mask on.
Keep more in your pocket for replacing in between breaks in the game, not during for any reason.
Try it and tell me your results.
You can thank me later by supporting my B/S/T threads on the money I saved you LOL
Seriously it works.
