Get the Helium instead
I have Mavic's Helium jersey and love it - perfect fit, really well made, etc. so I got this in the same size. Big (pun intended) mistake. This jersey is at least a size larger. 3-4 inches longer in back. The back panel of the Helium is material that does not stretch up/down so jersey does not sag if pockets are loaded. This does not, and the fabric is very light and stretchy so it sags dramatically with anything in the pockets. Esp. at this price, there are better choices out there.
