I was wondering if anyone knows if the CBUK shirts are like nike smalls or JL mediums
Just for size

I've bought a few CBUK shirts for my boyfriend, and he absolutely LOVED them! I think the fit is pretty true to size. The shirts have a very similar fit to banana republic. I would say, if you are normally a medium, buy a medium. They have a modern fit, but not tight in any way. They wash very well too (no shrinking!). I bought the CB Drytec Charter Polo and the Interlock Full Zip from fairwaystyles.com. Hope this helps!
