Castelli Trasparente Due Wind Jersey

The Trasparente Due Wind Jersey has become an instant best seller the moment Castelli designers released it into the wild. The Trasparente fires on all cylinders. It has a wide range of use which appeals to many riders, it is low volume and lightweight, has a tailored fit and the graphics are simply perfect. This product was designed to perform during efforts on the bike and as such it carries Castelli's Rosso Corsa designation.

In modern cycling apparel design, there is a bridging of the gap between jersey and jacket. Although you might think this to be an easy task, it requires a lot of thought and consideration, as well as proper fabric selection. And the last bit is the tricky part. Proper fabric selection is really code for proprietary fabric creation. This means developing purpose built fabrics and textiles to make low volume, race ready garments like the Trasparente Due work in the field on a daily basis without issue. In the case of this product, the proprietary fabrics are Windstopper X-Lite Plus and Warmer fabrics.

The Trasparente 's front panel uses the Gore-Castelli Windstopper X-Lite stretch textile. It offers up complete wind and water protection from inclement weather, wind and road spray. What makes this product so special is that is breathes and permits airflow and moisture control. The main body of the Trasparente features the Castelli specific Warmer fabric. This fabric seems to have found the right equilibrium of volume, loft and elasticity. It has a thin fleece backing and is super low volume. All of these panels are anatomically cut for a form fitting garment. Expect a fairly snug fit with just enough room for some layering garments. There will be no sag of material bunching. The Trasparente Due was designed to be an semi-aerodynamic garment.

Castelli kept the frills to a minimum which always works for us. You get the standard 3 rear storage pouches and one small zippered chest pocket. A full length YKK Camlock zipper adorns the front panel and helps with body temp regulation. There is also a small tab sewn to the bottom of the front of the jersey to make zipping and unzipping a snap. Elastic cuff and waist with silicone backing helps keep the jersey in place while riding.

You can decide if this is a jacket or jersey. What we can tell you is the Trasparente offers the perfect nexus of different materials working as one to provide you with a well-functioning, low volume garment that performs to task with every outing. It's a staff favorite and widely considered in the industry as Castelli's opus.
