The Mens Banff Springs Vest from Jack Wolfskin, keeps your torso warm while leaving your arms free to move. With its understated lumberjack style, this gilet also looks cool in the city. The Mens Banff Springs Vest is extremely warm. Because Jack Wolfskin has combined a duck down fill with a windproof outer fabric. Because they've used extra warm synthetic insulation on the shoulders and because the collar is extra high and has soft, cosy Lining. This means that light rain, snow and sleet simply bead up and run right off the outer fabric. And the synthetic insulation in the shoulders maintains its insulation performance even when damp.
