p>The Syntax MIPS is a "clean sheet of paper" design that incorporates the Roc Loc 5 Air adjustable fit system directly into the MIPS liner. The result is a lighter, better-fitting helmet compared to similarly-priced competitors. The 25 Wind Tunnel vents found throughout the Syntax MIPS keeps the wearer cool and comfortable on sweltering days. The larger "smokestack" vents at the top of the helmet assist in releasing heat during hard efforts at a slow pace. A Multidirectional Impact Protection System -or MIPS- system allows the Giro Syntax to better absorb the energy of an oblique impact. Four sizes, not three, make the Syntax MIPS a better fit for a wider range of road riders.
The MIPS liner does not extend the lifespan of any helmet beyond the initial crash. If your helmet is damaged in an accident, replace it.
