Giro Helios Spherical Helmet in Stone

Season:All Year Round

Brand:Giro

Code:38955-224

The Giro Helios features high-performance innovation for core road cyclists, gravel enthusiasts, and adventure riders. The heart of the design is Spherical Technology, which utilises a ball-and-socket design powered by Mips, the market-leading brain protection system that can help to reduce rotational forces. Spherical Technology allows the helmet's outer liner to rotate around the inner liner during a crash, and also allows Progressive Layering of the inner and outer liners to provide more comprehensive protection and performance.

In addition to advanced head protection, the Helios's 15 Wind Tunnel vents provide exceptional cooling power, enhanced by the patented Roc Loc 5 Air fit system and plush, antimicrobial Ionic+ padding for sweat absorption and permanent odour protection.

Advanced Protection:

  • Spherical Technology: The ball-and-socket design, powered by Mips, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash. It also eliminates contact with hard plastic or slip-planes against the skin.
  • Progressive Layering: Giro helmets with Progressive Layering use two different density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management.
  • MIPS Brain Protection System: Designed to reduce as much energy as possible while meeting and exceeding stringent safety standards.

Fit and Cooling:

  • Wind Tunnel Internal Channeling: Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.
  • Roc Loc 5 Air Fit System: This revolutionary fit system enhances cooling, fit comfort, and stability. It suspends the helmet slightly off the skull, allowing cool airflow to pass directly over the head.
  • Ionic+ Padding: Pure silver provides natural, permanent odour protection to help keep the helmet feeling fresh.

Technical Specifications:

  • Certification: CE EN 1078
  • Weight: 270g (size M)
  • Materials: 42% EPS, 24% PC, 16% Nylon, 5% Polyester, 4% POM, 2% PU, 6% Fiberglass, 1% Silicone
