Giro Helios Spherical MIPS Bike Helmet

Two EPS Foam Liners with Progressive Layering

Polycarbonate Shell with Hardbody Lower Shell

In-Mold Construction – In-mold construction fuses a tough polycarbonate outer shell with the helmet’s impact-absorbing foam liner. The fusion process allows Giro to sculpt better ventilation systems, so In-mold helmets can be lighter and cooler than traditional helmets.

Progressive Layering™ – A dual-density liner designed to address high- and low-speed impacts, for more comprehensive energy management.

Roc Loc® 5 Air Fit System – Using a patented design that suspends the helmet just slightly off the top of the skull, this system allows cool airflow directly over your head, enhancing the venting of heat out of the helmet. Fit and feel adjustments mimic the Roc Loc 5, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds, using a single hand.

Wind Tunnel™ Ventilation – Giro helmets are developed utilizing the proprietary Wind Tunnel™ ventilation system, which combines active vents with internal exhaust channels that thrust cool, fresh air over and around the riders head-while forcing heat and stale air out. This significant increase in air channeling makes a difference that riders will immediately feel and appreciate.

MIPS® Spherical – MIPS® Spherical is a pair of foam layers that work like a ball and socket to redirect impact energy in a crash. The system uses two distinct layers of foam within the helmet, rather than a single layer of foam and plastic liner. One layer is EPS, which is well suited to high-speed crashes. The other is a lower density EPP foam with rebound characteristics that offer protection in low speed impacts.

IONIC+ Padding – Pure silver is the ingredient that gives IONIC+ the power to provide natural, permanent odor protection to help keep your helmet feeling fresh.
