the size chart measurements are correct as of the most recent jersey! ask me about it! i have a hard time finding my size. this is a nice jersey for me. the material, as described as the LG website, is second class, air dry instead of cool dry. it is better than the 2nd class brand names i got from bicycle website discounters. for myself, it is the correct combination of size, color, and fit that i was looking for, so the 2nd class air dry is ok.
