I used this lock and it works quite well. Nice and small enough to store in your board jacket without any bulge or extra weight. Only complaint is that if you mess around with it too much the cord can get stuck inside the lock so that it won't go in any farther. Not a big deal as I somehow fixed it, but something to be aware of.
I got these goggles in red/black...the mirror was cool, they looked awesome, but i didn't get a chance to see how they performed on the mountain.
However, I ended up returning them because the frame of viewing was a lot more restricted than my old goggles, which cost about half as much as these. I would like to emphasize these goggles are mainly for those with smaller faces.
