I got myself this jacket it twice, once for the summer in size M and for the winter in size L. In summer Desk where you start with a shirt or T-shirt and then suddenly comes to a cold front. Then the jacket fits perfectly on the shirt and immediately receives the heat. In winter to a trip in the snow and have a slightly thicker sweater underneath can. The jacket material seems durable, the jacket section I would describe as a more fitting and not far, the jacket in L is a bit longer than the jacket M, but not much further. In the Jackets the way a bag is. Absolutely lightweight warm outdoor jacket recommended.
