Agreed -- that was my main reason for purchasing the Combyn. I'm not aware of any other soft-shell / multi-impact helmets on the market right now. I'm guessing we'll see a bunch next season, but Giro seems to be leading on this front at the moment. I did a quick google search to confirm my suspicions and I couldn't find any other helmets. I'm sure there has to be something, but I couldn't find any.
I'm not a helmet expert, so I can't say if the soft sell offers maximum protection, etc. It is functional, comfortable and appears to work from my own personal experience. Fortunately, I haven't had any head on collisions or other hard slams directly on my head yet and I hope to keep it that way. The Combyn gives me the peace of mind that I'm at least protected if something unexpected were to happen.
