Giro Syntax MIPS.
Giro's MIPS liner and in-mold construction with the same Roc Loc 5 Air fit system found in helmets costing three times as much.
The Verdict.
Gavler Meta-Score
“The Syntax MIPS democratizes helmet safety. At $100, it puts Giro's MIPS liner, in-mold construction, and Roc Loc 5 Air fit system within reach of every cyclist. You don't need to spend $250+ for rotational protection — the Syntax proves that the technology that matters most is available at a fraction of premium pricing.”
The Gavler Verdict
Precision Engineering
MIPS Liner
Proven slip-plane rotational protection, built into the design rather than added later to keep the shell low-profile.
Roc Loc 5 Air
Single-dial fit system holds the helmet slightly off the head to create airflow, and fine-tunes tension and tilt.
In-Mold Construction
Polycarbonate shell bonded to EPS foam during manufacturing for lightweight, effective impact distribution.
Technical Specifications
The Scoreboard
Outstanding value proposition — community ratings exceed expert scores because riders appreciate accessible safety technology. Weight and ventilation are adequate rather than exceptional.

Global Critique
“A decent, low-profile helmet with a lot of features at an affordable price point.”
“The 25 vents kept me cool with great airflow throughout my rides... what is sacrificed in aerodynamics is more than made up for in ventilation and cooling.”
“A well-ventilated, comfortable helmet that deals well with all kinds of road riding.”
