The Fly Kinetic SE helmet is made from a durable and lightweight polymer shell with a dual-density EPS (Expanded Polystyrene) liner. Three shells and four EPS sizes provide a precise fit and give superior aerodynamics, and this weighs 1342 grams +/-25g (size LG). It also comes with a custom-moulded rubber trim with an integrated nose guard and removable and washable comfort liner and cheek pads to absorb sweat while providing ventilation. It also comes with Fly Racing's True Functional Ventilation (TFV)— when in motion, air is forced through multiple air intake vents, passed through aligned vent channels in the EPS and exits out multiple rear exhaust vents. It also comes with a soft fleece helmet bag.
