I did. I'll post my observations and ask those on Sunday's ride to do the same after they try some on. I'm 6'2", 233 lbs. My extra weight is in my belly. I'm debating between a slightly tight 2x and a very comfortable 3x. I'll bring them all on Sunday. The largest size they have in their sample kit is a 4X, so some may have to go off the size charts flavored by comments of others as to general sizing trends.
