Technologies:

Ceramic Shell:
– All Alpina Helmets Manufactured Using The Inmold Process Are Fitted With A Robust Ceramic Shell. A Polycarbonate Plate Is Stretched Under Intense Heat Onto The Shape Of The Helmet In The Making And Pressed Onto The Hi-Eps Body Under High Pressure And Thermally Bonded To It. The Ceramic Shell Is Characterized By Several Qualities: It Is Impact- And Scratch-Resistant, Uv-Stable And Antistatic.

Hi-Eps:
– The Inner Shell Of All Alpina Helmets Is Made Of Hi-Eps (High Expanded Polystyrene). The Material Has Microscopically Small Air Chambers That Absorb The Forces Acting On The Helmet In The Event Of An Impact. Hi-Eps Provides Optimum Protection And At The Same Time Allows For Extra-Thin Helmet Wall As Well As Narrow Helmet Shapes.

Inmold:
– In The Inmould Production Process, The Polycarbonate Upper Shell Is Thermally Bonded To The Hi-Eps Inner Shell Of The Helmet Body Under Intense Heat And Pressure. This Creates A Large And Inseparable Connection Between The Upper And Lower Shell. Advantage: The Helmet Is Very Light And At The Same Time Extremely Stable.

Run System Ergo+:
– The Run System Enables All Alpina Helmets To Adjust To A Custom Size By Using An Easy-To-Move Dial. The Valuable Run System Ergo+ Has Two Large Wing-Shaped Head Supports That Make It Comfortable To Wear. The Difference From The Run System Ergo Pro: The Head Supports Do Not Have Rubber Coating.
