Love having an out of the way spot to store, and defrost goggles. Says it has an extra pocket for your belt, but doesn’t fit without wrapping it up like a pretzel. And then takes up too much of the goggle bag space. And would be a real pain to access in a pinch. I store belt in tunnel bag. Whole thing is kind of a pain to install but not terrible. Overall it’s worth it to me to have extra dry goggles in a safe spot. Doesn’t seem to effect engine cooling at all.
