Riding on gravel often means a little bit lower speeds and often a higher intensity level, and as a result breathability and temperature regulation become even more important. Our Unlimited Thermal Jersey uses our Warmer brushed fleece fabric on the body and mid-weight Warmer X-Stretch on the sleeves. The mix of fabrics makes for a wide temperature range, while the fabric itself lets just enough air in to keep you dry but not chilly. We've also made sure to keep this piece very functional for the demands of gravel riding. The gripper at the waist keeps the jersey in place, and the three pockets on the back provide enough storage for hours of riding.
