If numbers are any indication of efficacy, the original Synchilla is among the hardest working jackets on the planet.  The iconic brand now rolls with two fabrics to build more freedom of movement into an undeniably warm style; one is 100% recycled, the other, 85%.  Y-joint sleeves reach high and wide as zippered handwarmer and chest pockets keep track of the essentials.  Comfort is automatic while laundering is simple -- even in a sink in Singapore.  There’s no reason not to own one across the seasons – and years – as there are few 16.4oz traveling companions this loyal.  Human or otherwise.
