We're proud to carry over many design elements from the famous 2012 Tour de France jersey into our 2013 line up. In 2013 we've added an argyle covered back of the jersey so that you can show everyone on the road your argyle spirit. As with all of our jerseys, the key design feature from Castelli is that the jerseys are cut to fit you while you are riding your bicycle! When you receive your jersey, get out on your bike and ride with it to make sure it will fit properly. We recommend two things to make sure that you do have the right fit: please size up from your regular non Castelli cycling jersey. If you normally wear a medium, you will be most comfortable with a large jersey. Don't worry, large jersey doesn't mean you've packed on extra weight, some of our pro riders are wearing a size large this year! We also recommend that you try this jersey on in a simulated riding position before you decide that it is too small for you. If you've had experience with sizing Castelli apparel in the past, you should be able to ride the same size in our team apparel.
