Helmets are meant to protect the wearer’s head by taking the impact. However, even a minor spill can diminish the protective qualities of a helmet, and after a major crash or blow the helmet needs to be replaced. This certainly makes sense with cycling helmets, but with winter sports helmets there is an alternative.
The Pro-Tec B2 Snow instead features multiple-impact rebounding foam under the shell that can reconstitute after a crash. This allows the helmet to be used time and time again. The downside to this budget minded helmet is that it has just 15 fixed vents and no adjustment, with no audio options. But those who want a helmet to last and last, let the Pro-Tech B2 Snow be the last word in brain buckets!
