The jacket arrived quite quickly, within the stated time frame. It is of decent quality, but there are some loose threads here and there that prevent the zip from closing properly. This is fairly easy to fix. Overall, it can be forgiven although I'd like the manufacturer to take note of this as I have not been the only one to notice it. As for the size: my height is 176 cm, weight 92 kg, and let's say I have a bit of a belly, so my usual size is L, which fits just right and you can even fit a jumper underneath. Although the sleeves are a little long, there are Velcro fastenings that compensate for that. If your measurements are the same, but you have a slimmer build, take an M. You'll be satisfied. Also, the zip is on the right, which is unusual, but you get used to it.
