Not only will you look good riding around in this Pan Am Championship jersey, but you will feel great! This jersey is very light and breathable which is is a huge pro if you're out getting some serious miles and lots of climbing. The three standard pockets on the backside provide plenty of space for phone/keys/card/snack/sunnies really anything you may need. The no-slip grip around the bottom of the jersey keeps it in place while moving around, no ride up! I am 5'5" athletic build and have 2 jerseys, one small one medium. The medium is perfect for layering over a long sleeve when the weather is a little cooler.
