Kinda cool, but the V1-Pro is a bad idea. The newer helmets are much, much better in both terms of safety and comfort. Another thing is that such a helmet is so old that it's questionable whether the foam is any use anymore. All the sweat, skin oils, UV, and brittleness from aging in general would make such a helmet most suspect. Other than that, it's cool.
I was in Moab for a few months and once saw Tom Ritchey. Didn't make a fuss about him, but he wasn't wearing a helmet. This is the last place for mtn. biking where I wouldn't wear a helmet. There are no soft falls there, everything is rock.
Ok, my soapbox just collapsed. I'm done.
That said, I've needed my helmet twice so far. Once when I didn't duck far enough under a tree leaning over the trail and other when I hit a tree head on (BUT...through no fault of my own. A so-so rider tried to pass me on a very difficult section in a race and I said, "Not" I didn't the word "HERE!" out. He collided with me and I was pushed off the trail into a downhill section of woods. I dodged the first four trees, but not the fiftth. I had to put that in as my ego doesn't allow that story with the "It wasn't my fault!" bit
