The 100% Aircraft 2 Helmet sets the standard for high performance protection. With its shell constructed from carbon fibre it's both incredibly strong and lightweight. A full carbon fibre shell features Patent Pending injection molded chin bar integration that strengthens the front area, it also features chinbar rear support for additional reinforcement. The entire helmet is lined with Dual Density EPS foam, injection molded with polycarbonate designed to absorb heavy impacts. As well as the EPS foam lining the Aircraft 2, 100% have added their proprietary SmartShock system which utilises 14 small rubber elastomers suspending the helmet around the head to better absorb linear and rotational impact energy. Ventilation across the Aircraft 2 is an absolute game changer, vents along the chinbar, forehead and top of the helmet pull in plenty of air while massive vents towards the rear of the helmet vent air out to ensure you stay dry and cool. Washable, moisture-wicking anti-microbial liners are comfortable on skin and easily removable for cleaning straight after a heavy session. The multi-point adjustable visor on the Aircraft 2 is designed to give you maximum vision without obstructing your goggles. Finally a sturdy D-ring buckle secures the helmet comfortably in place even when it's tightened right up. The Aircraft 2 is tested and certified according to ASTM (F1952-15), CPSC (16 CFR 1203), CE (EN 1078:2012+A1:2012), and AS/NZS (2063:2008) Bicycle Standards. Sizing: Medium: 57-58cm (Cheek pad 25mm, Liner 10mm) Large: 59-60cm (Cheek pad 30mm, Liner 14mm)
