Frequently Asked Questions

What is MIPS technology in Giro helmets?

MIPS is a low-friction layer inside the helmet that slides 10-15mm in any direction during impacts, reducing harmful rotational forces by up to 40% compared to non-MIPS designs. It's standard in our featured Giro models.

How do I choose the right size for a Giro helmet?

Measure your head circumference above the eyebrows (e.g., 54-61 cm for most universals). Use Giro's size charts; their Roc Loc systems allow fine-tuning for a snug fit without pressure points.

What warranty does Giro offer?

Giro provides a one-year manufacturing warranty plus a lifetime crash replacement policy, offering discounted replacements if your helmet is damaged in a crash—contact their support for details.

Giro vs. other brands: Why go Giro?

Giro leads in MIPS integration and fit innovation, outperforming many in comfort tests. Versus competitors like Bell or Smith, Giro offers better value for MIPS-equipped MTB and rec helmets.

Which Giro model is best for beginners?

The Register MIPS II (adult or women's) is ideal—affordable, comfortable, and MIPS-protected for casual riding, with easy adjustability.
