this is ingenious although doesn't the banana blacken and get really squsihy? I enjoy a banana as much as the next guy when skiing but I have always had the "exploding banana in the pocket" syndrome.
I like this idea but what if you are carrying a tin of sardines for lunch?
I find the helmet requires tape to carry the lunch. I've taped on a hamburger once to the top. It works fine as long as you don't fall. Really, a big hat is far better to carry lunch as it has the storage in the top. The lunch also turns the hat into a semi-padded hat. Not as safe as a full padded hat, but pretty good. For lunch duties, I vote hat superior.
