This energetic, lightweight charger is bound to be a female favorite thanks to Liberty’s bamboo core. The bamboo core makes for a poppy yet solid ski, constructed from a relatively sustainable material. A double bonus. The gradually raised tip, camber underfoot and fl at tail result in another great any-time, any-condition ski. Testers said the Envy “charges through the crud,” a true test of a big-mountain ski’s mettle.
