Giro Synthe with MIPS


$270, Giro.com
The draw: Safety features and extreme ventilation

Giro claims that extensive testing in the wind tunnel showed that this helmet is nearly as efficient as the top-performing time-trial helmets. Two features that really stood out: an internal “roll cage” that provides added stability around the head, and even internal airflow via 26 vents. The extra $20 for the MIPS safety technology—Multi-directional Impact Protection System (intended to absorb both linear and rotational forces in the event of a crash)—is a worthy spend.
