Ah, the joys of summer. Sunny days, long rides, the opportunity to mitigate the dreaded cyclist tan line on the arm. Sleeveless jersey's may not always be appropriate, but when you want to wear one, you really want to, so it is great to have a sweet option in the closet. With the Entrata 2 Sleeveless Jersey FZ, Castelli has worked to deliver a comfortable, supportive jersey that wicks away moisture and feels great on the skin, while hugging the rider's physique for a clean, aero feel. No major compromises, yet full of performance on every level. And you can start to blend that tan line.

Today's technical fabrics are amazing in how well they can be constructed to offer compression, stretch, and moisture transfer, but the key to performance in these areas is fit. The best fabrics require skin contact to actively do their work properly, so the availability of a loose fitting, comfy jersey of the past has been curtailed. The Entrata 2's fabric is called Prosecco 3D, a proprietary material that is incredibly soft on the skin and is woven into 3D structures. The outer edges rest against the skin, gently pulling moisture off the body while more airy center sections carry it away, as well as bring cool air in. Skin contact is crucial to this process, meaning a loose fit jersey just can't function as well. The hydrophilic fibers refuse to hold moisture, so it spreads out over a larger area, and is forced to leave. That this fabric can be so light, with stretch and support, while doing it's job, is a feat of textile engineering. With the Entrata 2 Sleeveless, the designers created panels that supply varying degrees and orientation of stretch for supreme comfort and light compression.

Yet Castelli didn't stop there. A stretchy fine, lightweight mesh has been added at the top of both shoulders for greater range of motion and active cooling. Mesh panels around the arm hole allow for freedom of movement, excellent ventilation, complement the stretch Prosecco 3D, and ensure a more active air flow in this heat-building zone. The opening itself has a clean finish that won't irritate your skin at any temperature. The final applications of the mesh are on the back; one at the base of the neck, and one under the rear pocket structure to quickly release heat and perspiration at the lower back.

Of course, the 3 section pro-style pocket is also a feature, with stretchy, roomy pockets that can be stuffed without impacting fit or function. The full length YKK® Vislon zipper is a rider favorite and truly functional even with such lightweight fabrics. With the Entrata 2, Castelli uses a colored version that matches the secondary colorway for added style and appeal. The lower rear hem is reflective for 180° visibility. There will always be cyclists who prefer a loose fit jersey. The Entrata 2 Sleeveless Jersey FZ is a comfortable design that is form fitting, but not restrictive or overly tight. At the same time, it's inherent performance characteristics come from the fabrics and design, which not only keep you cool and dry, but ensure the jersey won't billow or catch the wind. The equates to less drag and better cycling performance. There are far too many riding days in a year when a sleeveless jersey is the preferred option, so when you buy one, you want performance and comfort that won't break the bank. The Entrata 2 is the perfect option by price, performance, fit, and style.
