I've got 3 of these jerseys, and i wish there were even more colors available. Sizing might be a bit tricky as other reviewers have mentioned. I'm 5'9" 160lbs. with a 39" chest and I wear a small (S/P). I could easily wear the medium as well, but I prefer the slightly tighter fit. The gripper elastic is great and the fourth pocket is very convenient to keep trash separated after eating on a long ride. Despite the thick feel of the fabric, this jersey is extremely well ventilated (maybe not on par with LG's top of the line, but it's remarkable for 1/3 the price).
