The best all around warm synthetic insulated jacket from Arc'teryx and the new replacement for the former popular Atom AR Jacket. A top pick for our Seattle Mountaineering Store for use in extreme wet weather when some customers will prefer a synthetic insulation layer.  Synthetic Coreloft™ insulation still retains the majority of its insulation value when wet.  This jacket is the warmest option in the Atom series from Ar'teryx, and can still be worn as either a midlayer underneath a rain shell or as your outermost layer like a lightweight belay parka.  Also works great underneath your waterproof ski shell for cold weather alpine lift skiing as well as being a perfect jacket for around town.
