A helmet that feels like it isn't there: the all-new Aries™ Spherical is like nothing before. Its sleeker form and lighter weight (only 270 grams in size medium, CE certification), deliver sensational comfort and cooling power. Spherical Technology™, our ball-and-socket design powered by Mips®, adds protection by redirecting energy away from the brain in certain impacts, and Progressive Layering with dual densities of Nanobead EPS foam adds more comprehensive energy management. 24 Wind Tunnel vents are maximized by the AURA II Reinforcement Arch, while a plush DryCore™ brow pad manages sweat and combines with a network of intricately engineered deep internal channeling to elevate comfort. From the proven reliability and adjustability of the Roc Loc® 5+ Air fit system, to full lower hardbody coverage to enhance durability, to the meticulous production quality, the Aries is state-of-the-art performance, protection, and style. - 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. HIGHLIGHTS - AURA II reinforcement arch - Ionic+™ anti-microbial padding - DryCore™ sweat management system - Eyewear docking ports Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older

There’s no easier or more effective way to patch a cut tire on the road or trail than carrying and using Park Emergency Tire Boots (3 per package). These thin, extra-tough patches peel and stick to the insides of tires to repair cuts and contain the tube until you can replace the tire.

Park's Gear Clean Brush has a handle on one end with a curved, serrated edge perfect for cleaning between cassette cogs. The other end's tough nylon bristles are ideal for cleaning the derailleurs, chain and other drivetrain parts to keep them clean and prevent premature wear. It also works great on brakes and other components that collect dirt and grime. The GearClean easily fits in a toolbox or pack.
