Hard Shell also known as outer shell, rain shell, waterproof layer, shell layer, wind shell. The hard shell layer is your armor against bad weather….snow, rain, sleet and wind are all blocked by the hardshell. It is your protection against the elements. \r\n\r\nThis jacket is made of water and wind-proof material (such as Gore-Tex®, eVent®, WeatherEdge®, or Dry.Q™ ) with an attached hood. Hard shell jackets don’t breath as well as other layers. This is your insurance policy that only leaves your pack in the worst conditions.\r\n
