Just bought two, one in blue and one in purple, a trad OCBD, the material is nice and thin, fits like Black Fleece/TB shirt.
Cool details - locker loop on the back and a nice button on the back of the collar. Some of the shirts have weird fabric and/or collars - me, I personally don't like club collars and think white collars on a casual shirt looks dumb. I went old school, will look great this summer with my RL Black Label shorts, a grosgrain belt and some flip flops.
I bought a large, fits great, nice and slim fitting. It fits a lot like the J Crew tailored fit, but shorter and better, if that makes sense. Made in the US of Fucking A!
Bloomies had a bunch on sale at the SF store.
