FWIW the 4 and 5 fit almost identical imo, just a bit longer in length and bigger arms. And haven't had a BoO shirt in a long time but wear medium in Gitman too. 5 may work for you

I couldn't find a BoO official thread so I'm posting here.
Anyone have these BoO chinos either khaki or navy?
1. How's the fit?
2. How's the quality? Are they thick and heavy or light? Durable?
3. Is the navy one really that dark as it is in the pics?
4. Do you know of a website where I can buy size 30 on sale right now?
In terms of fit, I have J Crew 484, Club Monaco modern slim fit, and Dockers Alpha khakis. Dockers is my favorite among these. How do BoO chinos fit compared to Dockers?
