Very good quality jacket, I love it. I love the look of it and the stitching looks very good. A great feature is the inside Key chain clip which is a great touch on the design. I'd say the buttons don't seem as durable as the rest of it but time will test their durability. Overall the quality is very good for the money and if you like the look of it don't hesitate to buy one, you won't regret it.
Size wise It took me a while to decide on the size to go for as I read the reviews and many said it could fit on the small side.
For reference to others to help decide.
I'm 5ft 8.5"/174cm tall with a 182cm/6ft wingspan, 70KG/155lbs weight with a 42" relaxed chest and 30" waist.
I went for the large which was also recommended on the website size calculator and it fit perfectly in length and across the shoulders with room to layer with a jumper underneath.
Hopefully that can help others decide sizing.
