I'm going out to Silverton field on the 17th for my first airsoft experience, well maybe, if they will have me,

Lets start with the face protection, I'm leaning towards mesh goggles and a mesh face mask, or full face mask with mesh eye pro, but I have heard of some vision issues with mesh eye pro and possible bb fragmentation.
So that would mean lenses, but then you get fogging, and therefore vision issues, and possible failure of the eye pro frames. I know myself well enough that my first reaction if they fog up will be to take them off, and that's bad if I'm on the field at the time. So I'm looking for a little detail on what these issues are and how frequent they happen.
Next, the boots, I'm looking for something around or below $50 that will hold up well in a combat environment, water proof doesn't matter, I can either make them waterproof with a water proofing product or just deal with wet feet if it comes to that situation, ill be bringing dry change of clothes just in case.
Last but not least id like to know some local locations in the Portland Metro area where I can buy these products, I cant order them online because I need them by the 17th. Any help will be appreciated, although you may be bringing about your own demise if I turn out to be good at this and meet you on the field.

Thank you,
Savage
