Quilted vests are great for warmth, but the Michelin Man shape and immobility? Not so much. So we replaced the marshmallows with sleek PrimaLoft Eco fill and oriented the stitching vertically and diagonally to flatter (not "fatter") your form. The knit-trimmed armholes and hem stretch and move when you move, and ease layering under a jacket. It's warmth without weight, cool beyond compare.
