Since several of you have asked for helmet advice in general here are two recommendations. For a good general overall helmet (disaster/rescue/climbing/caving) one cannot go wrong with either Petzel Petzel Helmet Petzel Helmet Petzel Helmet or Pacific Helmets NZ Pacific Helmets NZ (available in the US without problems). There are many companies that sell either or both brands, check around on the Internet to find the best price. As to models, again, there is some personal choice, but both of these brands offer application specific or good general helmets.
