From the early morning coffee run, up to the lifts, through the powder, and back down to the dinner party... The QSJ is a certified quiver killer. 120 grams of insulation provides significant warming power, but is still low profile enough to keep you from looking like a marshmallow. Hand pockets and a zippered chest pocket keep your digits warm and your phone secure. It’s like a jacket, gone undercover as a shirt, on a mission to catch the cold off guard and shut it TF down.
