CLASSIC PROFILE : A unique, highly distinctive & well balanced helmet shape to deliver the necessary ergonomic & acoustic properties of the Davida Jet.
CLOSE FIT: To create the Jet's incredibly snug & stable fit that eliminates lift at speed, The Jet is shaped to precisely match the natural contours of the head. Together the design of the shell & interior deliver the ergonomics required to ensure the width of the helmet below the ears & around the jaw is sufficiently narrower than at the temples.
SUPERIOR INTERIOR SOUND PROOFING : The additional use of our unique sound proofing EPU, extending uninterrupted from above the temple all the way down to the jaw line, reduces wind noise to an insignificant level. The Davida Jet has a worldwide reputation for being the quietest helmet available.
SUPREMELY LUXURIOUS COMFORT : Maximised by using more than 1 sq metre of the finest grade leather which is generously quilted to create the beautifully crafted, unbeatable richness & supremely comfortable fully leather lined interior that's finished with a pure satin crown.
PROPORTIONALITY: Using 3 shell sizes to create the 6 different helmet sizes reduces the overall weight & size to an absolute minimum. The smaller your size the smaller the shell size. The Jet is therefore the most efficient size and weight.
UNPARALLELED CHOICE: 100 highly distinctive colourways applied by hand. Choose 5 studs for peaks & visors at no extra cost.
SIZING: An additional Half Sizing Kit is available to fix the helmet interior to reduce the size & achieve a personal fitting.
