About that, I'm not sure how strong that stuff really is ?
And I don't know personally if Bigfoot would allow anything but paintball goggles, but since it's an airsoft field, it's polices might be different, So I'll check with them.
Thanks for all the replies, I'll look into it.
Edit: Just checked FVA website. It says "Only goggles that seal the face are allowed" and "Mesh goggles are allowed, but requrire safety glasses to be worn underneath". This might be a problem since I wear glasses.
