I actually had never thought of that, that could be a good idea. I know some helmet companies say to NEVER wear a hat under it because of potential danger, but don't know if it is actually dangerous. I think a summer helmet would work as long as you could comfprtably fit a hat in it. Go to a ski helmet site nad ask somebody there or chat with Backcountry.com if you still want more info. Hope this kinda helps.
