. Giro pioneered the aerodynamic helmet category with the original Advantage in 1985 and now theyre redefining it with the Aerohead Ultimate MIPS Helmet which is their fastest time trial helmet ever. Giro leveraged every resource available to create a helmet that tops the podium in speed, weight, style and comfort The shell is made of TeXtreme carbon fibre, an advanced material that's lighter and stronger than other carbon composites. The wrap around eye shield offers an unblocked field of view with a huge aerodynamic benefit and the shield is made by Zeiss Optics for supreme clarity.A magnetic anchor attachment keeps the shield secure, yet easy to remove or store in the flipped up position. Other stand out features include a Roc Loc Air fit system and a hydrophilic antimicrobial brow pad that absorbs up to 10x the amount of sweat compared with other standard urethane pads. This helmet is also equipped with the MIPS system to redirect impact energy, providing more protection from certain crashes Features Included Accessories Helmet pod for travelling, Second clear shieldConstruction Hybrid Construction, TeXtreme carbon fibre shell with in moulded EPS linerFit System Roc Loc AirVentilation Vented Shield, Over brow ventilation, Internal channellingSuper Fit engineeringEye shield made by Zeiss OpticsMagnetic lens anchor attachmentMIPS technologyHydrophilic padding with X Static antimicrobial fabricWeight 450gTechnologies. TeXtreme Carbon Fibre A Lighter, stiffer & stronger shell. TeXtremes wide and flat fibres fit closer together than conventional round carbon fibres and require less of the resin used to bind fibres together. In the case of the Advance MIPS, TeXtreme enabled Giro to create an ultralight shell thats tougher, stiffer and stronger than Giros offered before. Most importantly, TeXtreme offers impressive high energy impact management X Static Fibre X Static fibres use natural silver to provide heat conductive and antimicrobial properties to help keep your hands warm, and your gloves free of odour causing bacteria and fungus Lenses By Zeiss Optics Shield With Magnetic Attachment The wrap around eye shield offers an unblocked field of view with a huge aerodynamic benefit and the shield is made by Zeiss Optics for unrivalled clarity. A magnetic anchor attachment keeps the shield secure, yet easy to remove, and it can be stored in the flipped up position MIPS All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giros MIPS equipped helmets is to reduce rotational forces What is MIPSMIPS is a Brain Protection SystemRotational motion can cause brain injuriesThe low friction layer allows a sliding movement of 1015 mm, in all directions, reducing rotational motion to the brain during impactMIPS adds protectionRoc Loc 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 Air allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channelling 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 Hydrophilic Padding The hydrophilic pad can absorb up to 10 times its own weight in water, helping you manage sweat while riding. The pad retains moisture to prevent sweat from dripping into your eyes, and then dries quickly. The antimicrobial X Static lining helps to reduce odour, keeping your helmet fresh Super Fit Engineering Giro's proprietary Super Fit sizing system is based on human scale factors data and over 25 years of handcrafting helmets. By creating helmet moulds in up to 4 adult sizes to match the human bodys form, their Super Fit sizes comfortably and securely fit riders and feel like they are custom made just for you Buy Giro Protection from Chain Reaction Cycles, the World's Largest Online Bike Store.
