This mid layer piece is lightweight warm and comfortable. In fact Polartec® Power Grid™ provides one of a kind worth to weight ratio. This is the kind of piece you'll love so much when you're out touring that you'll find yourself wearing it even on days when you're not. Full hood designed to be worn under your helmet. Seems moved off the shoulders so they are not uncomfortable with a pack. Single check pocket with small mesh pocket inside. Thumb loops to keep sleeves down and the cold out.
