I am writing this review based up on my real life experience on 3/14/10.  My husband is a lifelong cyclist.  Together we have worn bike helmets our entire adult lives.  Friends joked about how we looked wearing our helmets in the past.  They don't joke anymore.  My husband was riding solo at about 18-20 MPH and became startled by an unleashed dog that appeared out of nowhere.  Expecting to be nipped at the heel, the dog instead crashed into the front bicycle wheel, sending him over the handlebars onto a paved street.  His 1 year old Schwinn Thrasher helmet took the fist impact, destroying itself in order to save his skull and brain.  Reconstructive orthopedic surgery was required for his shattered left collarbone.  He is still healing -  but he is able share his experience with others today.  I spent a mere $20 bucks at a discount store.  The Schwinn Thrasher helmet saved my husband's life.  Thank you Schwinn.
