I've got a sandbox helmet. I've used Dragons Rogues and Electric EG2.5's on it. Both of them, I had to tilt the helmet back a little bit to get them to fit right. EG2's I don't think will work with the bill that comes off the helmet since the 2.5's require some tweaking of the helmet. Cool looking helmet, but not as google friendly as others.. I ended up buying a Salomon Brigade this year, but mainly because I wanted audio back in the helmet. You will have to try on the goggles with the Sandbox to see exactly what I'm talking about.
