Jason G.wrote a review of Castelli GPM Short Sleeve Jersey on July 28, 2013
Familiarity: I've used it once or twice and have initial impressions
This jersey is definitely constructed with the "fit"rider in mind, and I am not entirely cut from that cloth. I am 5'8", 180 lbs, and semi-fit, but that didn't stop me from ordering it. I originally ordered a size up from my usual Large and the XL was just a little to snug. I exchanged for a XXL and that fit fine. A Sleek Italian design procured from quality materials makes this one of my favorite jerseys!
