Received my navy Schneider shirt jacket today, and I was glad I sized up to a V. (I'm a slim US 38/EU 48.) Like razl said, the fabric's very nice but it's heavy enough to make me wonder if it'll be too hot in 30+ Celsius weather. The jacket's awesome regardless.
Also received my Inis Meains. Again, sizing up worked for me. (Took these in medium instead of small.) I expect to begin wearing them in a week or so when temperature rises above freezing more often.
