I got the Servolo jacket, which is a seriously short jacket - really, more like a cropped mandarin style cardigan than anything else. I also like the Torceo jacket, and the rope toggle shawl collar Burchiello. They always have great knit jackets and cardigans in deep, warm, colors. The stuff is all cut short and slim. If you want a more relaxed fit, you can always easily size up one. I sometimes size up one. If not, as for the Servolo, I balance it out with baggy jeans. Otherwise, you can easily end up looking like a Thom Browne. victim circa 2007. Just don't ever think of the stuff as actually sports jackets. For example, I've never seen the "blazers" actually worn with the collars down. I mean, they don't even have the pretense of a melton. The Servolo, in particular, is best to be thought of more like a modified cadet jacket/cardigan than anything else. On me, at a very normal 5'11", that jacket hits barely under my belt line. Some of the other, 3 button jackets, hit about 1/2 way down my butt - not CM approved.
Of all the different materials, I like their double thinkness wool jersey, which is a staple every FW season, best.
If you are looking for less knits, and more fabrics like pressed and boiled wools, and a more structured look, Harris Wharf London is another alternative, though they have fewer models. They are growing (this is their 6th season), while Barena has been around for literally decades.
