Haven't you wasted enough time rolling up your sleeves? This vest makes that annoyance a thing of the past, while providing plenty of warmth along the way. It's made from a warm wool, polyester blend and lined with 100% cotton chambray. The insulation is down and there are plenty of pockets for stashing phones, headphones, and your increasingly cold fingers. The full button closure keeps out the chill, and the whole number breathes so you won't get too sweaty while keeping warm.
