The Trabec is made in a few different versions, and this one, the Race MIPS, is perhaps the most protective of them all. In addition the polycarbonate shell and the standard Aramid net within the EPS foam, the Race MIPS gets an expanded Aramid net to help reduce helmet breakup in the event of a major crash, as well as MIPS technology, which allows the helmet’s core to rotate slightly relative to its shell.
