Description
Whether you’re grinding gravel or riding distance on roads, the Giro Agilis MIPS® offers the perfect blend of airy, lightweight design and extended coverage. Engineered for riders who demand performance across multiple surfaces, this helmet prioritises both a sleek profile and robust protection.
At its core, the Agilis uses In-Mold construction, fusing a tough polycarbonate outer shell with an impact-absorbing foam liner. This process creates a helmet that is significantly more durable and better ventilated than traditional designs, without adding unnecessary bulk.
Key Features:
- Integrated MIPS® Technology: Designed to reduce rotational forces during certain impacts, providing an extra layer of protection for your brain.
- Roc Loc® 5 Fit System: The industry gold standard for comfort. Easily adjust fit tension and tilt with one hand for a secure, "skull-hugging" feel.
- Wind Tunnel™ Ventilation: 32 internal channels pull cool air in while pushing heat out, keeping you comfortable even on the steepest climbs.
- Hardbody™ Lower Wrap: The outer shell extends inside the helmet rim for enhanced durability and a premium finish.
Size Guide:
To find your perfect fit, measure the circumference of your head starting about an inch above your eyebrows.
| Size | Head Circumference (cm) | Head Circumference (in) |
| Small | 51 – 55 cm | 20” – 21.75” |
