I'm with you Cusepak... I also like the aerodynamics of the fit with elastic, but it is also a necessity because I carry so much in my pockets (mostly food - I'm gluten and casein intolerant and I can't count on finding food that I can eat when I'm riding). In my elastic-free jerseys I find that the stuff in my pockets bounces up and down and is extremely annoying and distracting when I ride. Also, I don't have to worry about my cell phone or wallet flying out!
