The “75” refers to the waist width, which is slightly thicker than similar 72 models in Atomic’s double deck product line. Between the individual decks lies an elastomer layer which reacts to pressure. When the skis are stressed the elastomer stiffens, therefore increasing stability while giving the rider better overall control on the slopes. This technology allows for increased maneuverability at low speeds, and can assist with acceleration out of turns. These skis come in a combination black and red design.
