The pinnacle down jacket from CMF this season the AR UL Down is an ultralightweight but supremely warm down jacket that can still be packed away when needed but keeps you toasty like a big jacket should. 

Made using a 90/10 Down which is incredibly lightweight and warm it is protected on the outside by a lightweight water repellent 20d nylon fabric and the inner is a tubular baffled style made in a lightweight 15d ripstop nylon. The jacket draws on influences from US military jackets and classic outdoor down jackets too. Double waterproof zipper keeps out any undesired wind and an elasticated draw cord hem helps you get locked in should you need it. Down filled adjustable hood helps keep your noggin warm when needed and there are some pretty sizeable hand warmer pockets too. You won't need another jacket all winter this one does the lot.
