A shirt has to be pretty interesting for me to go beyond Uniqlo, W+H, RRL or various forum affiliates - all of which are less than JE. For me that pretty much means Geller, Dries, Visvim, Schneider, and some SLP/MMM.
Looks like Eric from 10 past 10 owns one and gave them a solid review. Better execution than say, the Bamford iteration recently profiled on Hodinkee. I'd have to fill a lot of other wants on my list before I got to one of these, but I can see the appeal. Price isn't that bad.
