This is a padded jacket using PrimaLoft insulation from GAP. The size is S, but the fit is a bit large, so I'm listing it as a size M. Actual measurements: Length 68cm, Shoulder width 46cm, Body width 56cm, Sleeve length 66cm. The size is comparable to a Uniqlo Ultra Light Down jacket in size M. I think it's warm because it uses PrimaLoft. There's some color transfer on the flap where the zipper touches, but it's not visible when worn.
