Helmet Size Guide
How to Measure
Use a soft measuring tape and wrap it around the widest part of your head — typically about 1 inch (2.5 cm) above your eyebrows and ears. Keep the tape level around the back of your head. If you're between sizes, we recommend sizing down or choosing a helmet with an adjustment system. However, for all KASK helmets, we recommend sizing up by 2cm.

Product Information
The Giro Grid Spherical is a lightweight, high-performance, unisex snow helmet engineered for both intense backcountry adventures and resort riding. Designed with Spherical Technology powered by Mips®, this helmet offers advanced protection from rotational forces. The Grid features an In Form 2 Fit System for precise adjustments, a seamless goggle interface, and some colors include plush interior comfort for warmth when desired.
- Mips® Spherical Technology: Reduces rotational energy on impact
- Weight: Ultra-light construction for backcountry and resort use
- Thermostat Control™ Adjustable Vents: Custom-tunable, external airflow control
- BOA 360° Fit System: Fully adjustable, dial-based fit
- Fidlock® Magnetic Buckle: Pinch-free, one-handed operation, even with gloves
- In Form 2 Fit System: Up to 6 cm adjustment with improved dial and stability
The Grid Spherical excels for its low weight without compromising protective features. The Grid's innovative ball-and-socket Spherical Technology powered by Mips® delivers next-level impact redirection.
Technology and Performance
The Grid Spherical stands out due to its use of Spherical Technology’s unique ball-and-socket design, powered by Mips®, which effectively redirects impact force away from the brain by allowing controlled movement between helmet layers during angled impacts. This reduces the risk of injury from rotational forces, which is a leading cause of concussion in snow sports.
The helmet is also equipped with the In Form 2 Fit System, a lighter, lower-profile adjustment mechanism that lets you fine-tune your fit within seconds, even while wearing gloves. Enhanced vertical tuning and seamless compatibility ensure your helmet and goggles work as a unit, preventing any gaper gap or slippage during aggressive activity.
Other performance-driven features include:
- Thermostat Control™ ventilation that adjusts airflow instantly with a discrete, low-profile button
- Plush Max fleece interior (on select colors), which dries quickly and feels soft for lasting comfort
