This Cerium Jacket is the premier lightweight down jacket from Arc'teryx.  This is also somewhat of a hybrid piece that combines 850 fill-power down with Coreloft™ synthetic insulation strategically placed in moisture prone areas.  Typically worn as lightweight outer insulation piece or as a midlayer underneath an over-sized waterproof hardshell jacket in colder or wet conditions.
