Description of Spyder Glacial Gore-Tex Jacket Take safety seriously, and take it with you every time you ski. The Glacier includes serious safety features like an ear-splitting US Coast Guard-certified whistle that's audible at 1000 meters. A SOS lining helps rescue teams identify you when in need; the jacket's interior has the international distress symbol of a white cross on a red background. Universal safety info, including body rescue signals, international emergency cell phone info, and distress Morse code is printed on the jacket's interior. We hope you never need any of this stuff, but it's there if you do.
