Designed for enthusiasts who push their limits on long rides or challenging terrain, this helmet delivers exceptional cooling, precise fit control, and integrated protection in a sleek, modern package.

Key Features
- Integrated Mips Brain Protection System: All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giro’s Integrated Mips-equipped helmetsālike the Cieloāis to reduce rotational forces during angled impacts, which are a leading cause of brain injury. By combining the Mips slip plane with the helmetās adjustable fit system, the Mips Evolve Core allows the helmet to rotate slightly relative to the head, enhancing both safety and comfort without compromising fit stability.
- Roll Cage Reinforcement: Roll Cage is an invisible web of lightweight yet durable reinforcement molded directly into the helmetās EPS foam liner. This internal structure enhances the helmetās structural integrity during impacts, helping it stay intact when it matters most. Unlike external reinforcements, Roll Cage remains completely hidden, preserving the helmetās clean lines and low-profile design while adding an essential layer of strength and resilience you wonāt noticeāuntil you need it.
- Wind Tunnel Ventilation: Developed using proprietary Wind Tunnel testing, the Cieloās ventilation system combines 22 strategically placed active vents with deep internal channeling. These elements work together to actively draw cool air across the riderās scalp while efficiently pushing hot, stale air out through exhaust ports. This results in superior airflow and temperature regulation, making it especially effective during long or intense rides where staying cool is critical to performance and comfort.
- Roc Loc 5 Air Mips Fit System: The micro-adjustable Roc Loc 5 Air Mips system offers enhanced stability and optimized airflow throughout the helmet. It allows riders to independently fine-tune vertical positioning and contact points, ensuring a customized, secure, and exceptionally comfortable fit tailored to individual head shapes and riding styles. Its ergonomic and compact dial makes on-the-fly adjustments quick and easy, even while wearing gloves.
- Ionic+ Padding: The interior lining features Ionic+ padding infused with pure silver ions, providing natural, permanent odor resistance. This innovative material keeps the helmet feeling fresh even after extended use, eliminating the need for frequent washing and maintaining hygiene over timeāideal for multi-day tours or intense training blocks.
