There's a lot of technology that goes into the Entrata Jersey. While technically the entry-level jersey in the Castelli collection, it has been engineered to incorporate as much race-level performance as possible while still offering unmatched value. It benefits from the aero learnings from Castelli's race R&D through the one-piece sleeves with aero-optimized seaming. Not only is it aerodynamic, it's also more comfortable thanks to the four-way-stretch Air Mesh fabric and raw-cut sleeve ending that's stretchy to fit every arm without constricting. The main body fabric is just the right weight to keep you cool, while the ProSecco treatment carries away moisture to keep you dry. It's stretchy for great fit and provides UPF 30 sun protection, filtering 97% of UV rays. Thoughtful design and functional details abound, like the stretch panel in the center pocket, the highly reflective insert on the pocket, the full-length easy-sliding YKK® Vislon® zipper, and the silicone gripper elastic to keep the back of the jersey in place. - Italian-made ProSecco body fabric with hydrophilic treatment to wick moisture away from your body - Air mesh sleeves in modified raglan pattern provide more comfort and better aerodynamics - Raw-cut sleeve endings lie flat and never constrict - Full-length easy-sliding YKK Vislon zipper - 3 rear pockets, with center pocket with extra stretch insert and reflective panel

For those rides when you don't need three pockets or sun protection on your shoulders, there's the Promessa Jacquard Bavette Top. This top is great for your evening rides at the height of summer, or when you're trying to get rid of your cyclist tan lines or want to look great at your SoulCycle class. The Bavette uses a new performance jacquard knit that brings the graphic directly into the construction of the fabric without compromising fit, stretch, moisture management or comfort. We've finished it off with a zippered pocket. - Jacquard-knit extra-wicking stretch fabric - 2-way stretch for great fit while holding pockets in place - Raw-edge elastic trim for straps and collar - Zippered rear pocket
