Castelli's Essenza Jersey features classic tailoring of natural fibers and complementary synthetics that deliver modern performance with an elegant design that evokes a classic look, simultaneously carrying some modern features and cycling specific details any rider will appreciate. The poly/wool fabric blend is as light as a modern synthetic fabric but with great moisture management and a natural look and texture. The logos are applied embroidered patches, the metal zipper pull is a quality detail, and even the internal elastic is colored to match the jersey fabric. It's a classic-looking performance jersey and a perfect match to the Premio product line overall.

The cut is slim, but comfortable, and the paneled structure has a natural taper in the sewing pattern. The visual adds an elegance, but is also carried purpose, helping maintain the fit and longevity of the fabric. The same can be said for the front and side waist hem, which offer stretch and hold for the same reasons, plus a clean transition. The complementary, yet contradictory, features that work well together include a traditional height collar, along side a more modern sleeve length. The three pocket system works well, and a droptail feature adds a little more structure, while a GIRO3 gripper elastic holds the rear hem in place. Castelli finishes the Essenza Jersey with evocative classic features with embroidered patch logos, and a metal zipper pull.
