A Clyde-worthy friend of mine is thinking about starting to ride. For now, I'm supplying him with loaner stuff, up to and including the bike, from the collection of "stuff that was cheap on Craigslist so I got it, just in case" that's taking over my basement.
One problem, though, is the helmet. That, of course, I don't want to trust to Craigslist: helmets are good for one fall only. With the ones I have at home, I'm having trouble finding one for him to borrow: his neck is significantly beefier than mine, and he has a fleshier lower jaw as well.
Any thoughts on an inexpensive helmet that works well for clyde-sized heads?
