I recently took a bad backwards fall and had an ice halo on. I apparently stepped on my blade while doing the the outside Mohawk in the Fourteen step. I went straight back on to my back. I believed the Ice Halo saved me from a serious concussion. However, I did manage to hit the upper back part of my head because the halo only provides about 2 inches of protection. So I decided to order the Crashe and give it a try because it seems to go higher onto the head, in the back. Once I received it I became concerned about how thin the padding is compared to the Ice Halo. The Ice Halo is much thicker (3-4 times), but the Crashe definitely provides a larger area of head protection. My husband who is a mechanical engineer, thinks that the Ice Halo will provide better impact protection due to the density of the padding. I am going to try and insert some additional padding in the Crashe. (probably between the plastic and the material.
