Weighing in at an impressive 85 grams, this flyweight jersey certainly ensures you aren't hauling around any extra material. It's crafted from a perforated material that helps maximize breathability and ventilation, while the woven ceramic material enhances UV protection. Usually, heading up climbs, we'll fully unzip the jersey, channeling our inner Richard Virenque as he danced on the pedals up Mont Ventoux. The truth is, our climbs probably aren't as steep as what Spotted Dick rode, and as great as it feels to rock a jersey unzipped, it isn't the best for aerodynamics. Keeping it zipped up is not only faster, it offers more support through its second skin fit and the ventilated panels allow air to enter the jersey providing cooling. The rear is designed not to sag even when the three pockets are filled up with all the necessaries for a long day on the bike, and the reflective piping along the lower hem helps with visibility if you're chasing the sun on the way back home.
