Aries Spherical Special Edition

Created in collaboration with Kasia Niewiadoma of Canyon-SRAM Racing, this exclusive Giro.com capsule draws inspiration from Kasia's dominance on the road, her deep connection to home in Poland, and the quiet details of her personal life and creative passions. Launching in the lead-up to the Tour de France Femmes, the collection blends traditional Polish florals and fabric motifs with transparent, layered graphic execution inspired by Polish glassware as a modern expression of Giro's pillar of radical transparency. Each piece carries Kasia's signature graphics as a custom mark, delivering a limited capsule that celebrates speed, heritage, and individuality through elevated design.

• AURA II REINFORCING ARCH — The shatter-resistant and translucent Aura II Reinforcing Arch runs throughout the helmet; bolstering structural integrity and allowing massive vents for cooling
• VIRGINIA TECH #1 RANKING — Researchers at independent testing facility Virginia Tech gave Aries Spherical their best score event in their rankings of which helmets best reduce the risk of injury. All Giro helmets with Spherical Technology have received their top level of 5 stars.
• DRYCORE™ — The DryCore™  sweat management system utilizes an internal silicone bead to redirect moisture away from the rider's brow and eliminate the irritation of sweat dripping into the eyes.
• SPHERICAL TECHNOLOGY — Spherical Technology's 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.
• 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 Mips-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to rider's brain in certain impacts.
• 21 WIND TUNNEL VENTS — Giro helmets are engineered with our proprietary Wind Tunnel venting system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust cool; fresh air over and around the rider's head while forcing heat and stale air out.
• DEEP INTERNAL CHANNELING — Combined with the massive vents; internal channeling forces air to flow over the scalp; providing remarkable cooling power.
• 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.
• EYEWEAR DOCKING PORTS — Integrated eyewear docking ports with rubber grippers help to secure sunglasses.
• REFLECTIVE DETAILS — Reflective Details enhance visibility at nighttime or in low-light conditions when illuminated by a light source; such as headlights; by returning the light back to the source and reaching the driver's eye.
• ROC LOC® 5+ AIR FIT SYSTEM — This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling as well as fit; comfort; and stability. Using a patented design that suspends the helmet just slightly off the top of the skull; Roc Loc® 5+ Air allows cool airflow to pass directly over your head; further enhancing the performance of vents and internal channeling that exhaust 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.
• IONIC+® PADDING — Pure Silver is the secret ingredient that gives IONIC+ ® the power to provide natural; permanent odor protection to keep your helmet feeling fresh.
