Amazing in hot weather
This jersey is robust but thin, and should be awesome in hot weather. Not thin and trapping like lycra, but breathably thin with lots of tiny tiny holes. The colors are definitely more subdued than the pictures due to the large amount of micropores in the fabric. I'm 5'10 194lbs and with a 42' chest, more of a thick build, and do have biceps unlike most cyclists... The large is a great fit. Close but definitely not race fit. I had to return the LG Mondo XL because it fit like a medium...
