You wanted the best, and our SL Race Jersey delivers. It represents everything we know about jersey design, and it checks all the boxes for how a premium jersey should perform. This is the SL Race. From start to finish, we spared no expense and thought of every detail down to the very last stitch.

Not only this, but the materials we used are incredibly soft against the skin for all-day comfort on the road. And, compared to the rest of the SL line, this jersey has some unique features, like our structured back panel and welded "cuffless" sleeve design that improves your aerodynamic profile and overall compressive comfort. Of course, you'll also find convenient features like three rear pockets, a zippered sweatproof pocket for housing your electronics, and a full-length front zipper.

Light. Dry. Fast. Racing in the Alps in July is for a select few, but the products that come out of that experience are absolutely amazing for the rest of us. We made this jersey for hot days in the high mountains, based on direct feedback from the pros. They wanted a jersey to keep them cool on hot days without sacrificing aerodynamics. The Climber's 4.0 Jersey uses the same CFD-based seam construction as our Aero Race 8S Jersey, but we've used the most aerodynamic 3D mesh fabrics we could find for optimal cooling. These fabrics also have a great soft and stretchy quality to them, giving this jersey a comfortable fit too, which you need for big days in the mountains. And since this jersey is meant to be used in the sun, we've also made sure the fabric on the back blocks 90% of UV rays. - CFD-based fabric placement and seam construction - Engineered rapid cooling, light weight, and aero efficiency - Airflow shoulder construction^Flusso 3D fabric on front - StradaPro 3D back for breathability - Elbow-length stretch sleeves with raw-cut edges - Elastic around the waist to keep the jersey in place and support pockets - YKK® Vislon® zipper - UPF 13

YOU WON'T EVEN NOTICE We've been riding our bikes on gravel since before it was a thing, and we've always done it in our normal Castelli jerseys. The only complaint was that the occasional branch or vine could pull the delicate fabrics, and after a few rides the jersey wouldn't look exactly pristine. That's what we focused on with the Fuori Jersey. It compromises nothing in terms of fit, comfort, moisture management and light weight, but we've used fabrics that offer additional protection from snags. The arms and shoulders are most exposed, and here we've used a stretch woven fabric that fits great yet is extremely protective. The main body is closer to a traditional jersey fabric but fared best in our snag and Velcro tests. We don't call this a gravel jersey because it's equally at home on the asphalt, but if you do take it on your favorite trail it'll hold up better than any road jersey, and better than most off-road gear. - The all-surface unlimited no-compromise jersey - ProSecco Unlimited main body fabric - Snag-resistant stretch woven on sleeves and shoulders - No-sew flat-edge sleeve finishing - 3 rear pockets - YKK Vislon zipper - Silicone gripper elastic at waist - 18°-32°C / 65°-90°F - Weight: 151g
